Obtain the roots of the following quadratic equation by using the general formula for the solution: $25x^2 + 20x + 7 = 0$.

(D) For a quadratic equation of the form $ax^2 + bx + c = 0$,the roots are given by the quadratic formula: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.
Here,$a = 25$,$b = 20$,and $c = 7$.
First,calculate the discriminant $D = b^2 - 4ac$:
$D = (20)^2 - 4(25)(7)$
$D = 400 - 700$
$D = -300$.
Since the discriminant $D < 0$,the quadratic equation has no real roots.
