X^2 + 3x + 25 = 0

Since the quadratic equation is not factorable

Then use the quadratic formula to solve it

X = [- b + sqrt(b^2 – 4ac)] / 2a

and

X = [- b - sqrt(b^2 – 4ac) ]/ 2a

X = [- 3 + sqrt(3^2 – 4(1)(25))] / 2(1)

X = [- 3 + sqrt( - 91 ) ]/ 2

X = -3/2 + sqrt( 91)i/2

So the other solution

X =  -3/2 - sqrt( 91)i/2
