(11x)(-9x)=99x
We move all terms to the left:
(11x)(-9x)-(99x)=0
We add all the numbers together, and all the variables
-99x+11x(-9x)=0
We multiply parentheses
-99x^2-99x=0
a = -99; b = -99; c = 0;
Δ = b2-4ac
Δ = -992-4·(-99)·0
Δ = 9801
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{9801}=99x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-99)-99}{2*-99}=\frac{0}{-198} =0x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-99)+99}{2*-99}=\frac{198}{-198} =-1
