Which polinominal is
a difference of 2 squares

The difference of two squares occurs when the middle term or "b" of your polynomial is absent. so the the "c" term would have to be the product of a single number, one positive and one negative. if c = 3 then x2 - 9 = 0 factors to (x+3)(x-3) = 0 and so on.

Step-by-step explanation:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
