How do you solve (2x-8) (4x+1)

8x^2-30x-8

Step-by-step explanation:

2x times 4x = 8x squared

2x times 1 = 2x

-8 times 4x = - 32x

-8 times 1 = - 8

8x quared + 2x + - 32x + - 8

= 8x squared - 30x - 8

At first you multiple 2x by 4x, than 2x by 1, than you do the same thing, but replace 2x with - 8. After you finished multiplication combine all the monomials together. The answer should be 8x2-30x-8
