Question

What’s the product (X+3)(x+7)

Answer 1

`{x }^(2) + 10x + 21`

Explanation:

`(x + 3)(x + 7) \\ = x * x + 3 * x + 7 * x + 3 * 7 \\ = {x}^(2) + (3 + 7) x + 21 \\ = {x}^(2) + 10x + 21`

Answer 2

The answer is x²+10x+21

(x+3)(x+7)

=(x+3)(x+7)

=(x)(x)+(x)(7)+(3)(x)+(3)(7)

=x²+7x+3x+21

=x²+10x+21
