simplify polynomial expressions -4(-3w-5) 2(-2w-8)

Sagot :

Answer will be -48w^2 - 272w - 320 Just Multiply it. :)
The first binomial:
-4 (-3w - 5) = 12w + 20

The second binomial:
2(-2w-8) = -4w - 16

The problem does not clearly say what to do with the binomials (what operation):

To find the product (the instruction is only to simplify, not solve for w):
(12w+20) (-4w-16) = -48w² - 272w - 320

To find the sum:
12w - 4w + 20 - 16 = 8w + 4

To find the difference:
(12w+20) - (-4w - 16)
12w + 20 + 4w + 16 = 16w + 36
