How to find the roots of a quadratic equation with leading coefficient greater than 1?

A quadratic equation in its generic form can be written as:
 ax ^ 2 + bx + c = 0
 For this case:
 a> 1
 For this case what you should do is use the following equation
 roots = ((- b) +/- root (b ^ 2-4 * a * c)) / (2 * a)
 answer
 root1 = ((- b) + root (b ^ 2-4 * a * c)) / (2 * a)
 root2 = ((- b) - root (b ^ 2-4 * a * c)) / (2 * a)
