Hi, I've got a review sheet due Monday in algebra and I really need some help with it!

Use quadratic formula to solve:

0=x(squared)-5x+6

0=x(squared)+x-10

Estimate the roots of the equation:

y=x(squared)-2x-8

y=x(squared)-4

Graph:

y>or equal to x(squared)

y<x(squared)-3

Hope I made that clear enough! Thanks!!!
