X2+X+2*2=49
We move all terms to the left:
X2+X+2*2-(49)=0
determiningTheFunctionDomain X2+X-49+2*2=0
We add all the numbers together, and all the variables
X^2+X-45=0
a = 1; b = 1; c = -45;
Δ = b2-4ac
Δ = 12-4·1·(-45)
Δ = 181
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{-(1)-\sqrt{181}}{2*1}=\frac{-1-\sqrt{181}}{2} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{181}}{2*1}=\frac{-1+\sqrt{181}}{2} $
