Question

Find the product of (x + 7)(x − 7). (1 point)

Answer 1

It products x^2 - 49. the answer is the second one

Answer 2

Answer:

X^2-49  is the correct option

Step-by-step explanation:

(x+7)(x-7)

x*x-7x+7x-7*7

x^2-49

The product of both gives x^2 − 49

which implies that option last option is wrong x^2+49 since the sign in between is negative sign

The option x^2 + 14x + 49  is also wrong because the -7x+7x gives zero not 14

The first option is also wrong because -7x+7x gives zero not -14

All in all, the correct option is x^2+49, the second option
