Question 134289: Please help me solve this. I know it is a polynomial operation and cannot figure it out. I know the area is lxw...I'm a bit fried right now
"The base of a triangle is 5 cm greater than the height. The area is 33cm^2. Find the height and the length of the base."
thanks.

You can put this solution on YOUR website!
let x=height, so x+5=base

area is 1/2 base times height __ 33=(1/2)(x+5)(x) __ 66=x^2+5x

x^2+5x-66=0 __ factoring __ (x+11)(x-6)=0 __ x+11=0 and x-6=0
