7x^2+224=-84x
We move all terms to the left:
7x^2+224-(-84x)=0
We get rid of parentheses
7x^2+84x+224=0
a = 7; b = 84; c = +224;
Δ = b2-4ac
Δ = 842-4·7·224
Δ = 784
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{784}=28$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(84)-28}{2*7}=\frac{-112}{14} =-8 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(84)+28}{2*7}=\frac{-56}{14} =-4 $
