Question

-2x^2+8x=-1

Answer 1

-2x^2+8x=-1
To make it a quadratic equation, add the -1 to the other side. So that makes it -2x^2+8x+1=0. You can then use the quadratic formula to solve for x.

Answer 2

a = -2, b = 8, c = 1
Quadratic Formula
x=[-b+or-(sqrtb^2-4ac)]/2a
Then just substitute.

Answer 3

Thanks all. I'm writing this down. Haven't done Quadratic Formula work yet.

Answer 4

\[x=[-8+(\sqrt{8^{2}}-4\times-2\times1)]\div2\times-2\]

Answer 5

No problem :) If you still have further questions, let me know.
