(3x-6)(5x-6)=52
We move all terms to the left:
(3x-6)(5x-6)-(52)=0
We multiply parentheses ..
(+15x^2-18x-30x+36)-52=0
We get rid of parentheses
15x^2-18x-30x+36-52=0
We add all the numbers together, and all the variables
15x^2-48x-16=0
a = 15; b = -48; c = -16;
Δ = b2-4ac
Δ = -482-4·15·(-16)
Δ = 3264
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{3264}=\sqrt{64*51}=\sqrt{64}*\sqrt{51}=8\sqrt{51}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-48)-8\sqrt{51}}{2*15}=\frac{48-8\sqrt{51}}{30} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-48)+8\sqrt{51}}{2*15}=\frac{48+8\sqrt{51}}{30} $
