Exercise 81 Page 103

To factor a perfect square trinomial, the first and last terms have to be perfect squares.

no

Practice makes perfect

To determine if an expression is a perfect square trinomial, we need to ask ourselves three questions.

Is the first term a perfect square? 9x^2= 3^2x^2=( 3x)^2 ✓
Is the last term a perfect square? 16= 4^2 ✓
Is the middle term twice the product of 4 and 3x? 8x≠ 2* 4* 3x *

As we can see, the answer to all three questions isn't yes. Therefore, we cannot write the trinomial as the square of a binomial.
