8x^2+52x+76=-4
We move all terms to the left:
8x^2+52x+76-(-4)=0
We add all the numbers together, and all the variables
8x^2+52x+80=0
a = 8; b = 52; c = +80;
Δ = b2-4ac
Δ = 522-4·8·80
Δ = 144
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{144}=12$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(52)-12}{2*8}=\frac{-64}{16} =-4 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(52)+12}{2*8}=\frac{-40}{16} =-2+1/2 $
