factor out first factor it will be neg. and divide-there will be one positive and one negative
sum of cube and square
factor out first it will positive and divide
Simplify radicals
Take out of radical by grouping sqrt out by 2, cubert out by 3, 4th root by 4, etc.
Find x-intercept and y-intercept
plug in zero-multiply out fractions-remember negatives
