(x+2)(2x-1)
USE THE FOIL METHOD: multiply the following:
F-first variables per quantity x and 2x = 2xsquared
O-outside variables x and -1= -x
I-inside variables 2 and 2x= 4x
L-last variables per quantity 2 and -1= -2
then combine:
2xsquared -x +4x -2=
2xsquared+3x-2
(3x+4)(-x+7)
F: 3x and -x= -3xsquared
O: 3x and 7 = 21x
I: 4 and -x= -4x
L: 4 and 7= 28
combine:
-3xsquared+ 21x -4x +28=
-3xsquared+ 17x +28
