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

  • math - ,

    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
