Question

Find the two products below. Compare and contrast, in complete sentences, the similarities and differences of the two.

(x + 4)(x − 4) and (x + 4)(x + 4)

anonymous · Answer

$$(x + 4)(x − 4) =x^2-4^2 =x^2-16$$
$$(x + 4)(x + 4) =(x + 4)^2 =x^2+2\times x \times4+4^2=x^2+8x+16$$

Could you explain how your answer?

you got*

anonymous · Answer

In order to find the product of (x+4)(x−4) we can use the formula $$(a+b)(a−b)=a^2-b^2$$
and to find the product of $$(x+4)(x+4)=(x+4)^2$$ we used the formula $$(a+b)^2= a^2+2ab+b^2$$
