$2x^2+7x+3=0$

Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 2x^2+x6x+3=0. Combining like terms x and 6x. 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=7 and c=3. Then substitute the values of the coefficients of the equation in the quadratic formula:<ul><li>\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}</li></ul>. To obtain the two solutions, divide the equation in two equations, one when \pm is positive (+), and another when \pm is negative (-). Subtract the values 5 and -7.

$x=-0.5,\:x=-3$
