Question

0 = -2x^2 + 8x + 4
Please help find the x intercepts of the graph?

Answer 1

\[x = 2\pm\sqrt{6}\]

Answer 2

2+\[\sqrt{6}\]

Answer 3

2-\[\sqrt{6}\]

Answer 4

Or what I said.

Answer 5

:)

Answer 6

thank youu! :)

Answer 7

First factor out a -2
--> -2(x^2 -4x -2) = 0
Then divide by -2 on both sides
--> x^2 -4x -2 = 0
Then use quadratic formula to solve for x
\[x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}\]
The solution is whats already been said
\[x = 2 \pm \sqrt{6}\]
