$3x^2+8x=9-5$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 3x^2+8x+5=9. Group the terms of the equation by moving the terms that have the variable x to the left side, and those that do not have it to the right side. Subtract the values 9 and -5. Rewrite the equation. To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=3, b=8 and c=-4. Then substitute the values of the coefficients of the equation in the quadratic formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}.
