$\frac{2x^2-5x-2}{x^3-5x^2+8x-4}=0$
Learn how to solve problems step by step online. Find the roots of (2x^2-5x+-2)/(x^3-5x^28x+-4). Find the roots of the equation using the Quadratic Formula. Multiply both sides of the equation by x^3-5x^2+8x-4. To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=2, b=-5 and c=-2. 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.
