Did you try it?

4x^2+11x+6.

Factors of 4

1*4
2*2

Factors of 6

1*6
2*3

There are only a few to try.  Try them!

4x^2 +11x +6
=4x^2 +8x +3x +6
=4x(x+2) +3(x+2)
(4x+3)(x+2)

comm.dan · Answer

I did it with 2x and 2x, my bad.

jim_thompson5910 · Answer

4x^2+11x+6


4x^2+3x+8x+6 ... 3 and 8 multiply to 4*6 = 24 AND they add to 11 (middle term)


(4x^2+3x)+(8x+6)


x(4x+3)+(8x+6)


x(4x+3)+2(4x+3)


(x+2)(4x+3)

comm.dan · Answer

I see what I did wrong I needed to do 4x and x.
