Anyone help me?? :)

How to solve:
5x2 = -(19/2x-1)
and
2x2 + 45/2x - 18 = 0


With full solutions? Thank you :)

  1. First of all, online "^" is used to indicate an exponent, x^2 = x squared.

    5x^2 = -(19/2x-1)

    Get rid of the parenthesis and multiply by 2.

    10x^2 = -19x + 2

    Move all terms to left side.

    10x^2 + 19x - 2 = 0

    Factor the two end values into two factors that will add to the middle value.

    (10x-1)(x+2) = 0

    X = -2, 1/10

    Use a similar process with the second equation.
