Question

How do you foil (16x–19)(8x–8)?

Answer 1

Answer:

128x^2-280x+152

Step-by-step explanation:

one trick i use is Front Outer Inner Last

Apply the method (a+b)(c+d)=ac+ad+bc+bd

16x*8x+16x(-8)+(-19)*8x+(-19)(-8)

Apply minus plus rule =(-a)=-a, (-a)(-b)=ab

=16*8xx-16*8x-10*8x+19*8

simplify: 16*8xx-16*8x-19*8x+19*8=(your answer)
