(3x+2)(3x+2)+2=66
We move all terms to the left:
(3x+2)(3x+2)+2-(66)=0
We add all the numbers together, and all the variables
(3x+2)(3x+2)-64=0
We multiply parentheses ..
(+9x^2+6x+6x+4)-64=0
We get rid of parentheses
9x^2+6x+6x+4-64=0
We add all the numbers together, and all the variables
9x^2+12x-60=0
a = 9; b = 12; c = -60;
Δ = b2-4ac
Δ = 122-4·9·(-60)
Δ = 2304
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{2304}=48$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(12)-48}{2*9}=\frac{-60}{18} =-3+1/3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(12)+48}{2*9}=\frac{36}{18} =2 $
