To find the roots of a polynomial of the form $ax^2+bx+c$ we use the quadratic formula, where in this case $a=\frac{1}{4}$, $b=-3$ and $c=-2$. Then substitute the values of the coefficients of the equation in the quadratic formula: $\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{3\pm \sqrt{{\left(-3\right)}^2-4\frac{1}{4}\cdot -2}}{2\frac{1}{4}}$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 1/4x^2-3x-2=0. To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=\frac{1}{4}, b=-3 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}. Simplify \frac{3\pm \sqrt{{\left(-3\right)}^2-4\frac{1}{4}\cdot -2}}{2\frac{1}{4}}. 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 3 and -\sqrt{11}.
