If it's not what You are looking for type in the equation solver your own equation and let us solve it.
x^2+x+15/4=0
We multiply all the terms by the denominator
x^2*4+x*4+15=0
Wy multiply elements
4x^2+4x+15=0
a = 4; b = 4; c = +15;
Δ = b2-4ac
Δ = 42-4·4·15
Δ = -224
Delta is less than zero, so there is no solution for the equation
