Solve the equation. (Enter solutions from smallest to largest. If there is no solution, enter NONE in the answer boxes.)
5x2 = 9x + 2

5x^2 = 9x + 2
first we transpose all terms to the left side of the equation:
5x^2  9x  2 = 0
then we factor (since it's factorable):
(5x + 1)(x  2) = 0
5x + 1 = 0
5x = 1
x = 1/5
x  2 = 0
x = 2
therefore,
x = 1/5 and x = 2
hope this helps~ XD
