m2+22m+120=0
We add all the numbers together, and all the variables
m^2+22m+120=0
a = 1; b = 22; c = +120;
Δ = b2-4ac
Δ = 222-4·1·120
Δ = 4
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{4}=2$$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(22)-2}{2*1}=\frac{-24}{2} =-12 $$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(22)+2}{2*1}=\frac{-20}{2} =-10 $
