Consider the common quadratic equation

Ax2 + bx + c = 0 whereas a ≠ 0

 The roots of the equation are obtained via the given formula as:

X = (-b + √(b2 - 4ac))/2a

Example                                 

Solve for x ia formula

5x2 + 2x - 3 = 0

Solution

a = 5 and b = 2 and c = - 3

X = (-b + √(b2 - 4ac))/2a

X = (-2 + √(22 - 4(5)(-3)))/2(5)

X = 3/5 or -1
