## anonymous 5 years ago how to solve an equation using factoring and quadratic formula ??? 2x^ - 8x = 0 ???

2x(x-4) x=0 x=4

okay

quadratic formula $x = (-b + - \sqrt{b ^{2}-4ac)})/2a$

4. anonymous

Using the formula. x= ($-b \pm \sqrt{b) ^{2}-4ac}$)/2a a = 2 b= -8 c =0 . Plug in and Solve

It factors easily enough.

thanks

Both methods should result in identical solutions.
