Solve This Equation: 3 4 9 0 + by claudetam is a document available to read on EtoBox.

To solve the equation 3x^2 + 4x - 9 = 0, first group like terms so it is 3x^2 + 4x - 9. Then set each side equal to 0 and factorize the left side into (3x + 3)(x - 3). Finally, set each factor equal to 0 and solve, resulting in the solutions x = -1 or x = 3.
