Factor the quadratic expression. x2 + 16x + 48
2 answers:
X² + 16x + 48 x 12 x 4 find factors of x² and 48, that would add up to 16x(x + 12)( x +4) is your answer, as using the FOIL method FOIL (first, outside, inside, last) x(x) = x² x(4) = 4x 12(x) = 12x 12(4) = 48 x² + 4x + 12x + 48 simplify x² + 16x + 48 (True) you're answer is (x + 12)(x + 4) hope this helps
I will do my best to explain this “ x method “ I use Basically, two factors of the first and last number must multiply together to sum up to equal the middle number 1 X 12 1 4 (x+12) (x+4) Hope this helps!
