Simplify the product. (x - 4)(x + 3)

OpenStudy (anonymous):

You would use the FOIL method. |dw:1364489427224:dw|

OpenStudy (anonymous):

like this x2 + x - 12

OpenStudy (anonymous):

it is x2-x-12 because the 3x-4x so subtract 4 from 3 that is -1 so it would be x2-x-12

OpenStudy (anonymous):

x2 - x - 12 got it

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

i put the the plus sign...lol

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

FOIL: First Outer Inner Last (x-4)(x+3) First: Multiply x * x Outer: Multiply x * 3 Inner: Multiply -4 * x Last: Multiply -4 *3 Add them together, and you got it!
