Question

Please help me solve this!!! 2x^2 -8x=3

Answer 1

heres the solution :)

Answer 2

Personally, I prefer using the quadratic formula isf the equation doesn't factor.
\[2x^{2}-8x-3=0\]a=2, b=-8, c=-3

\[x=(-b\pm\sqrt{b^{2}-4ac})/2a=(8\pm\sqrt{64+24})/4=(8\pm2\sqrt{22})/4=4\pm(\sqrt{22}/2)\]
Which is the same answer, but, in my opinion, in a pretty form.

Answer 3
