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 – 6x + 9
x2 – 2x + 4
x2 + 5x + 10
x2 + 4x + 16

Answer 1

Answer:

a. x2 – 6x + 9

Step-by-step explanation:

In order to solve this you just have to try and factorize the options and the result should be two exact binomials. Remember that the formula for perfect square trinomial is:

So we only have to factorize x2-6x+9=

As you can see, a is equal to X, and b equals 3:

(x-3)(x-3)=x2-6x+9

SO this is a perfect square trinomial.

Hope this helps Have a good day
