$2x^2+8x+11=0$
Learn how to solve equations problems step by step online. Find the roots of 2x^2+8x+11. Find the roots of the polynomial 2x^2+8x+11 by putting it in the form of an equation and then set it equal to zero. 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=8 and c=11. 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. To obtain the two solutions, divide the equation in two equations, one when \pm is positive (+), and another when \pm is negative (-).
