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 $a=121$, $b=-176$ and $c=64$. Then substitute the values of the coefficients of the equation in the quadratic formula: $\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{176\pm \sqrt{{\left(-176\right)}^2-4\cdot 121\cdot 64}}{2\cdot 121}$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 121x^2-176x+64=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=121, b=-176 and c=64. 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 176 and 0.
