Factor 5x - 15 factor -8x - 40

Mathematics
1 answer:
Ahat [919]2 years ago
8 0
5x-15 after factoring out the 5 you will get 5(x-3) because 15 divided by 5 is 3 so for the first one the answer is 5(x-3)
-8x-40 after factoring out the -8 you will get -8(x-5) as 40 divided by 8 is 5

Hope that helps have a good day! :)

    5x³ + 8x² - 7x - 6

1)

x + 2 is a factor because when using synthetic division, the remainder is zero.

-2  |  5    8    -7    -6

    <u>|  ↓   -10    4     6 </u>

       5   -2    -3     0  ← remainder is zero

2)

x + 2 is not a factor because when using synthetic division, the remainder is not zero.

-1  |  5    8    -7    -6

    <u>|  ↓  -5    -3     10 </u>

       5   3    -10    4  ← remainder is not zero
