Question

factor 3x^2+2x-8 step by step?

Answer 1

hello?

Answer 2

3x^2+2x-8=0
ax^2+bx+c=0
you want to look for 2 numbers that multiply to (a times c) and add to b
so that would be two numbers that multiply to -24 and add to 2
in this case -4 and 6, these will become your new coefficients of x for b
3x^2 +6x -4x -8 =0 ,now you can factor by grouping
3x(x+2)-4(x+2) =0
(x +2)(3x-4)=0
x= -2 , x= 4/3

Answer 3

thank you
