Specify the solving method
To find the roots of a polynomial of the form $ax^2+bx+c$ we use the quadratic formula, where in this case $a=225$, $b=-360$ and $c=144$. Then substitute the values of the coefficients of the equation in the quadratic formula: $\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{360\pm \sqrt{{\left(-360\right)}^2-4\cdot 225\cdot 144}}{2\cdot 225}$
Learn how to solve equations problems step by step online. Find the roots of 225x^2-360x+144=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=225, b=-360 and c=144. 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 360 and 0.
