4x^2=135+12x
We move all terms to the left:
4x^2-(135+12x)=0
We add all the numbers together, and all the variables
4x^2-(12x+135)=0
We get rid of parentheses
4x^2-12x-135=0
a = 4; b = -12; c = -135;
Δ = b2-4ac
Δ = -122-4·4·(-135)
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$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-12)-48}{2*4}=\frac{-36}{8} =-4+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-12)+48}{2*4}=\frac{60}{8} =7+1/2 $
