To find the roots of a polynomial of the form $ax^2+bx+c$ we use the quadratic formula, where in this case $a=9$, $b=-12$ and $c=4$. Then substitute the values of the coefficients of the equation in the quadratic formula: $\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{12\pm \sqrt{{\left(-12\right)}^2-4\cdot 9\cdot 4}}{2\cdot 9}$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 9x^2-12x+4=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=9, b=-12 and c=4. 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 (-). Add the values 12 and 0.
