Factor the expression.

A. ++

(x+4) * (x+3)

Step-by-step explanation:

To factor the general expression:

X²+ax+c

We need to find the numbers b and d of the factoring expression:

(x+b) * (x+d)

Where:

b*d = c

b+d = a

For the expression:

X²+7x+12

We need to find b and d that:

b+d = 7

b*d = 12

If b = 4 and d = 3, the expression could be:

(x+4) * (x+3) = X² + 4x + 3x + 12 = X² + 7x +12

why can't you?
