Its even better since you got it wrong too.
4x^2-2x-8x+4
4x^2-10x+4
general terms are much better for things like this
(ax + b)(cx + d) = acx^2 + adx + bcx + bd |

first = 4x * 2x

outside = 4x * 3
last = 5 * 3
(4x + 5)(2x + 3)
im pretty sure thats it, but its been awhile. why dont you just do a google search on this stuff or check your math book? |
if you look carefully...FOIL is just distribution of ()
PS..this website will help you from 7th grade right through college
calc101.com<---- use it wiesly because if you gotta show work on a test then don't rely on this 100% of the time.:whip: |

easy way to factor
lets see
ax+bx+c=0 correct?
multipy a and c, then figure out the factors of that, then figure out from those factors, if added, equal b
example
x2 + 6x = 9x = 0
-9 x 1 = -9
factors of -9 are {1, 3, 9}
3 x 3 = 9
therefore, (x + 3)(x + 3)
or something
it's been too long since algebra 1
don't take me serriously, cuz i'm probably wrong
