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

Answer:
(a) Micah's solution is wrong.
Step-by-step explanation:
After adding 5/2x to both sides, Micah should have obtained ...
5/6 = 8
This would indicate there are no values of x that make the statement true.
Answer:
the answer would be y^6/x^2
Step-by-step explanation:
so (Y) to the sixth power over (X) to the second power
Y+x=6
y=x^2-6x+6
You would have to expand the second one.
y=x*x-6x+6
and you add all of the x's
y=-6x^3+6
y+x=6
Solve the one that's in y=mx+b form.
And you should be able to solve it from there.
Not sure I have had idea of what it is but I don’t wanna give u the wrong answer
