Question

Bailey writes the expression g^2 + 14g + 40 to represent the area of a planned school garden in square feet. What factors can be used to find the dimensions of her garden?
(g−4)(g−10)

(g+4)(g+10)

(g+4)(g−10)

(g−4)(g+10)

Answer 1

Answer:

(g + 4)(g + 10)

Step-by-step explanation:

Note that 10*4 = 40 (which is the constant in g^2 + 14g + 40) and that 10 + 4 = 14 (which is the coefficient of x in g^2 + 14g + 40).

Thus, g^2 + 14g + 40 factors into (g + 4)(g + 10) (second answer choice).
