Question

A perfect square trinomial can be represented by a square model with equivalent length and width. Which polynomial can be represented by a perfect square model? x2 â€"" 6x 9 x2 â€"" 2x 4 x2 5x 10 x2 4x 16.

Answer 1

A perfect square trinomial is represented by the equation $x^2-6x+9$ and this can be determined by using the factorization method.

Given :

A perfect square trinomial can be represented by a square model with equivalent length and width.

The following steps can be used in order to determine the polynomial that can be represented by a perfect square model:

Step 1 - First, check option a) $x^2-6x+9$ is a perfect square or not.

Step 2 - Try to factorize the above equation.

$x^2-6x+9 = x^2-3x-3x+9$

$x^2-6x+9 = x(x-3)-3(x-3)$

$x^2-6x+9 = (x-3)^2$

Step 3 - The equation in option a) represents the perfect square trinomial.

From, the above steps, it can be concluded that the correct option is a).
