Question

Solve the equation 4x^2-45x+225=15x+7. Is there a formula im supposed to use? How do i start

Answer 1

subtract 15x and 7 from both sides so you have it set = 0

Answer 2

\[4x^2-45x+225=15x+7\]
\[4x^2-60x+218=0\]

Answer 3

and do the quadratic formula after?

Answer 4

now maybe divide by 2 and get
\[2x^2-30x+119=0\] will make solving easier. yes, then the quadratic formula
