12x^2-15x-63=0
a = 12; b = -15; c = -63;
Δ = b2-4ac
Δ = -152-4·12·(-63)
Δ = 3249
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{3249}=57$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-15)-57}{2*12}=\frac{-42}{24} =-1+3/4 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-15)+57}{2*12}=\frac{72}{24} =3 $
