Question

factor 6x^2-x-1
then tell meh what you did lol.

Answer 1

6x^2-3x+2x-1
=?

Answer 2

i factored by grouping

Answer 3

(2 x-1) (3 x+1)

Grouping

Answer 4

oh totally.

Answer 5

ax^2+bx+c
a=6
b=-1
c=-1
find factors of a*c that have product a*c and have sum b
a*c=6(-1)=-6=-2(3)=2(-3)
b=-1=-3+2
bx=-3x+2x
replace!
6x^2-3x+2x-1
now factor by grouping
3x(2x-1)+(2x-1)
(2x-1)(3x+1)

Answer 6
