To factor a perfect square trinomial, the first and last terms have to be perfect squares.
no
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.
