To find the roots of a polynomial of the form $ax^2+bx+c$ we use the quadratic formula, where in this case $a=6$, $b=12$ and $c=6$. Then substitute the values of the coefficients of the equation in the quadratic formula:
- $\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-12+\pm 0}{12}$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 6x^2+12x+6=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=6, b=12 and c=6. 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 0 and -12. Subtract the values 0 and -12.
