Consider the equation y=-x^2-7x+12

y = (x + 4)(x + 3)

Step-by-step explanation:

y = x ^2 + 7x + 12

The two numbers must add up to 7 and has a product of 12, and since the equation is all positive, then the two numbers are positive too.

So y = (x + 4)(x + 3) is the answer.

Check:

y = (x + 4)(x + 3)

y = x(x + 3) + 4(x + 3)     distributive property

y = x^2 + 3x + 4x + 12

y = x^2 + 7x + 12
