Please Help! Maths exam coming up. Solve: 2x(5-x)=8 Thanks :)

[From: ] [author: ] [Date: 11-09-06] [Hit: ]
..x=1 or 4-I honestly dont know...I got up to 10x-2x^2=8 and couldnt figure it out.......
Please show all your working. Thanks to anyone who helps me!

Distributive property.
10x-2(xsquared)=8
Move it over to get 2(xsquared)-10x+8=0
Factor out... (2x-2)(x-4)+0
x=1 or 4
