Answer:1.00
Step-by-step explanation:
I think it's B but if I where you I would wait until someone else comments on here to so you know for sure
F(x) = x² + 4x + 10
f(x) - 10 = x² + 4x
perfect square:
x² + 4x + 4 ⇒ (x + 2)²
(x + 2)² = x(x+2) + 2(x+2) = x² + 2x + 2x + 4 = x² + 4x + 4
f(x) - 10 + 4 = x² + 4x + 4
f(x) - 6 = (x+2)²
f(x) = (x+2)² + 6
three squared minus two thirds

three square = 3 x 3 = 9

Least common factor of 1 and 3 is 3

Three squared minus two third is twenty five by three.
