6x^2+7x+9=11x^2
We move all terms to the left:
6x^2+7x+9-(11x^2)=0
determiningTheFunctionDomain 6x^2-11x^2+7x+9=0
We add all the numbers together, and all the variables
-5x^2+7x+9=0
a = -5; b = 7; c = +9;
Δ = b2-4ac
Δ = 72-4·(-5)·9
Δ = 229
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{-(7)-\sqrt{229}}{2*-5}=\frac{-7-\sqrt{229}}{-10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+\sqrt{229}}{2*-5}=\frac{-7+\sqrt{229}}{-10} $
