Question

Solve each equation by factoring: 5r^2-44r+120=-30+11r
35k^2-22k+7=4

Answer 1

First question:
5r^2-44r+120=-30+11r can be transformed into:
\[5r^2-55r+150=0\]
Take out the 5 as a common factor before factoring,

Second question:
35k^2-22k+7=4 can be transformed into:
\[35k^2-22k+3\]

If you see an equation that might be capable of being in the format \[ax^2 + bx + c = 0\], don't hesitate to try to turn the current equation into this format, then use either the Quadratic Equation or factoring to solve the equation.
