To find the roots of a polynomial of the form $ax^2+bx+c$ we use the quadratic formula, where in this case $a=\frac{669}{4}$, $b=-\frac{8058}{25}$ and $c=111.256$. Then substitute the values of the coefficients of the equation in the quadratic formula:
- $\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{2}{669} \frac{8058}{25}+\pm 171.638919$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 669/4x^2-8058/25x13907/125=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{669}{4}, b=-\frac{8058}{25} and c=111.256. 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 \frac{8058}{25} and -171.638919. Add the values \frac{8058}{25} and 171.638919.
