Specify the solving method

1

To find the roots of a polynomial of the form $ax^2+bx+c$ we use the quadratic formula, where in this case $a=25$, $b=2$ and $c=5$. Then substitute the values of the coefficients of the equation in the quadratic formula:

• $\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-2+\pm \sqrt{-496}}{50}$

$x=\frac{-2+\pm \sqrt{-496}}{50}$

Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 25x^2+2x+5=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=25, b=2 and c=5. 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 (-). Calculate the power \sqrt{-496} using complex numbers. Calculate the power \sqrt{-496} using complex numbers.
