9x^2=5-7x
We move all terms to the left:
9x^2-(5-7x)=0
We add all the numbers together, and all the variables
9x^2-(-7x+5)=0
We get rid of parentheses
9x^2+7x-5=0
a = 9; b = 7; c = -5;
Δ = b2-4ac
Δ = 72-4·9·(-5)
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*9}=\frac{-7-\sqrt{229}}{18} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+\sqrt{229}}{2*9}=\frac{-7+\sqrt{229}}{18} $
