BRAINLIEST Multiply each side by the common denominator

c. x² + 2x -5 = 0

Step-by-step explanation:

 Given expression;

            =  

Unknown:

 The quadratic equation equivalent to this expression:

Solution:

  The common denominator here is 3x;

    So, multiply both sides by 3x

          x 3x  =   3x

          5 x 3 = (x + 2)x

           15 = x² + 2x

     So;

          x² + 2x - 15

The quadratic expression is x² + 2x - 15
