What is 7+10x-2x-2=-3
Ivahew [28]
7+10x-2x-2=-3

—-Combine like terms...10x-2x=8x and 7-2=5

8x+5=-3
——subtract 5 on both sides.. the 5’s will cancel each other and -3-5=-8

8x=-8
——Divide 8 on both sides...the 8’s will cancel out and -8 divided by 8 = -1

Answer: x = -1

How do you solve 8n squared+4n-16= -n squared using the quadratic formula?
klemol [59]
8n² + 4n - 16 = -n²
8n² + n² + 4n - 16 = -n² + n²
9n² + 4n - 16 = 0
n = <u>-4 +/- √(4² - 4(9)(-16))</u>
                     2(9)
n = <u>-4 +/- √(16 + 576)</u>
                   18
n = <u>-4 +/- √(592)
</u>              18
n = <u>-4 +/- 24.33</u>
              18
n = -<u>4 + 24.33</u>        n = <u>-4 - 24.33</u>
             18                           18
n = <u>20.33</u>                n = <u>-28.33</u>
         18                            18
n = 1.1294              n = -1.57389
