22=42x-4.9x^2
We move all terms to the left:
22-(42x-4.9x^2)=0
We get rid of parentheses
4.9x^2-42x+22=0
a = 4.9; b = -42; c = +22;
Δ = b2-4ac
Δ = -422-4·4.9·22
Δ = 1332.8
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-42)-\sqrt{1332.8}}{2*4.9}=\frac{42-\sqrt{1332.8}}{9.8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-42)+\sqrt{1332.8}}{2*4.9}=\frac{42+\sqrt{1332.8}}{9.8} $
