x^2+13x*42=0
Wy multiply elements
x^2+546x=0
a = 1; b = 546; c = 0;
Δ = b2-4ac
Δ = 5462-4·1·0
Δ = 298116
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{298116}=546$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(546)-546}{2*1}=\frac{-1092}{2} =-546 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(546)+546}{2*1}=\frac{0}{2} =0 $
