# What is the meaning of square of trinomial?

## What is the meaning of square of trinomial?

A perfect square trinomial is a special kind of polynomial consisting of three terms. The square roots of two of the terms multiplied by two will equal either the negative or positive version of the third term.

### How do you explain a trinomial?

The definition of a trinomial is a math equation that has three terms which are connected by plus or minus notations. An example of trinomial is 6x squared + 3x + 5.

#### Why are trinomials called perfect squares?

Expressions of this form are called perfect square trinomials. The name reflects the fact that this type of three termed polynomial can be expressed as a perfect square!

Is x2 18x 81 a perfect square?

x2−18x+81 is a perfect square trinomial.

Which constant term makes the trinomial a perfect square?

To complete the square, you use the fact that all perfect square trinomials have a similar form. For instance, consider the following perfect square trinomials. In each case, note that the constant term of the perfect square trinomial is the square of the half the coefficient of the x-term.

## What is a trinomial example?

A trinomial is an algebraic expression that has three non-zero terms. Examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z. 2a2 + 5a + 7 is a trinomial in one variables a.

### What is an example of a perfect square trinomial?

A perfect square trinomial is an algebraic expression that is of the form ax2 + bx + c, which has three terms. It is obtained by the multiplication of a binomial with itself. For example, x2 + 6x + 9 is a perfect square polynomial obtained by multiplying the binomial (x + 3) by itself.

#### How do you write a perfect square trinomial?

An expression obtained from the square of a binomial equation is a perfect square trinomial. An expression is said to a perfect square trinomial if it takes the form ax2 + bx + c and satisfies the condition b2 = 4ac. The perfect square formula takes the following forms: (ax)2 + 2abx + b2 = (ax + b)

How do you identify a trinomial?

You call an expression with a single term a monomial, an expression with two terms is a binomial, and an expression with three terms is a trinomial. An expression with more than three terms is named simply by its number of terms. For example a polynomial with five terms is called a five-term polynomial.

What is example of perfect square trinomial?

## How do you express a trinomial?

A trinomial is an algebraic equation composed of three terms and is normally of the form ax2 + bx + c = 0, where a, b and c are numerical coefficients. The number “a” is called the leading coefficient and is not equal to zero (a≠0). For instance, x² − 4x + 7 and 3x + 4xy – 5y are examples of trinomials.

### What is the formula for a perfect square trinomial?

What is the Formula for Perfect Square Trinomial? A perfect square trinomial is obtained by multiplying two same binomials. It takes the form of the following two expressions. They are, (ax) 2 + 2abx + b 2 = (ax + b) 2 (ax) 2 −2abx + b 2 = (ax−b) 2

#### What is a trinomial in math?

In mathematics, a trinomial is an algebraic expression that has three terms and takes on the form a + b + c. The terms a, b, and c can be numbers, variables, or some combination of the two.

What are the Special Products of square trinomials?

The difference of squares, the sum of cubes, and the difference of cubes are other polynomials that fall into the special products category. The unique pattern with perfect square trinomials is that their factors consist of the repetition of one binomial. Perfect square trinomials are a vital component of the completing the square algorithm.

What is the square of the sum of three or more terms?

The square of the sum of three or more terms can be determined by the formula of the determination of the square of sum of two terms. Now we will learn to expand the square of a trinomial (a + b + c). Let (b + c) = x. Then (a + b + c) 2 = (a + x) 2 = a 2 + 2ax + x 2. = a 2 + 2a (b + c) + (b + c) 2.
