Answer:
-4 ± 2√6
Step-by-step explanation:
Rewritten in standard quadratic form, x^2+8x-2=18 becomes x^2 + 8x - 20 = 0.
Here the quadratic coefficients are a = 1, b = 8 and c = -20 and so the discriminant is b^2 - 4ac, or 8^2 - 4(1)(-20), or 96.
Because the discriminant is positive, we know that this quadratic has two different real roots. These roots are:
-b ± √(b² - 4ac)
x = -------------------------
2a
which in this case comes out to:
-8 ± √96 -8 ± 4√6
x = ------------------ = ------------------- = -4 ± 2√6

Answer:
The second choice
Step-by-step explanation:
Answer:
1/6, 2/3, 15/18
Step-by-step explanation:
get a common denominator
2/3 times 6
15/18 times 1
1/6 times 3
new fractions : 12/18, 15/18, 3/18
so it would be 3/18, 12/18, 15/18
then just revert it back to the original fraction and you have your answer
Answer:
it will be 0
Step-by-step explanation:
x+y+2 = 0
x³+y³+2³ = 0
*8=2³
