$x^2+5x-25-5=0$
Learn how to solve problems step by step online. Solve the quadratic equation x^2+5x-25=5. Grouping all terms to the left side of the equation. Subtract the values -25 and -5. To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=1, b=5 and c=-30. Then substitute the values of the coefficients of the equation in the quadratic formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}. Simplifying.
