(x*x)+x-122=0
We add all the numbers together, and all the variables
(+x*x)+x-122=0
We add all the numbers together, and all the variables
x+(+x*x)-122=0
We get rid of parentheses
x+x*x-122=0
Wy multiply elements
x^2+x-122=0
a = 1; b = 1; c = -122;
Δ = b2-4ac
Δ = 12-4·1·(-122)
Δ = 489
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{489}}{2*1}=\frac{-1-\sqrt{489}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{489}}{2*1}=\frac{-1+\sqrt{489}}{2} $
