5x^2-7x+7=9
We move all terms to the left:
5x^2-7x+7-(9)=0
We add all the numbers together, and all the variables
5x^2-7x-2=0
a = 5; b = -7; c = -2;
Δ = b2-4ac
Δ = -72-4·5·(-2)
Δ = 89
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{89}}{2*5}=\frac{7-\sqrt{89}}{10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7)+\sqrt{89}}{2*5}=\frac{7+\sqrt{89}}{10} $
