(9x-31)(6x-2)=(3x+33)
We move all terms to the left:
(9x-31)(6x-2)-((3x+33))=0
We multiply parentheses ..
(+54x^2-18x-186x+62)-((3x+33))=0
We calculate terms in parentheses: -((3x+33)), so:We get rid of parentheses
(3x+33)
We get rid of parentheses
3x+33
Back to the equation:
-(3x+33)
54x^2-18x-186x-3x+62-33=0
We add all the numbers together, and all the variables
54x^2-207x+29=0
a = 54; b = -207; c = +29;
Δ = b2-4ac
Δ = -2072-4·54·29
Δ = 36585
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{36585}=\sqrt{9*4065}=\sqrt{9}*\sqrt{4065}=3\sqrt{4065}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-207)-3\sqrt{4065}}{2*54}=\frac{207-3\sqrt{4065}}{108} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-207)+3\sqrt{4065}}{2*54}=\frac{207+3\sqrt{4065}}{108} $
