Question

solve by factoring
3x^2+20x+12=0

Answer 1

3x^2 + 20x +12=
(3x + 2) (x + 6)

Answer 2

are those all the steps you took

Answer 3

first you figure out for 3x^2 which would be (3x+?)(x+?)
then you have to figure out what times what = 12 ( 6 and 2)
after that you put them in the equation (3x+2)(x+ 6)
if you want proof that it equals 3x^2 +20x+12 then multiply the two equations together.
