**Jai**, Sunday, January 22, 2012 at 8:31pm5x^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
