-16x^2+48x+64=0
a = -16; b = 48; c = +64;
Δ = b2-4ac
Δ = 482-4·(-16)·64
Δ = 6400
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{6400}=80$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(48)-80}{2*-16}=\frac{-128}{-32} =+4 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(48)+80}{2*-16}=\frac{32}{-32} =-1 $
