Answer:
x = -4 + 3√2 and x = -4 - 3√2
Step-by-step explanation:
Complete the square of x^2+8x-2=0:
Between 8x and -2, write in 4^2 - 4^2, so that we now have:
x^2 + 8x + 16 - 16 - 2 = 0, or by writing x^2 + 8x + 16 as the square of a binomial, (x + 4)^2 = 18
Taking the square root of both sides, we get:
x + 4 = √18 = ±√9√2, or ±3√2
Then x = -4 + 3√2 and x = -4 - 3√2
The answer is 22.976

Answer:
-3/2+√29/2 or -3/2-√29/2
