-4a^2+15a+44=0
a = -4; b = 15; c = +44;
Δ = b2-4ac
Δ = 152-4·(-4)·44
Δ = 929
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(15)-\sqrt{929}}{2*-4}=\frac{-15-\sqrt{929}}{-8} $$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+\sqrt{929}}{2*-4}=\frac{-15+\sqrt{929}}{-8} $
