12x^2+8=4x+56
We move all terms to the left:
12x^2+8-(4x+56)=0
We get rid of parentheses
12x^2-4x-56+8=0
We add all the numbers together, and all the variables
12x^2-4x-48=0
a = 12; b = -4; c = -48;
Δ = b2-4ac
Δ = -42-4·12·(-48)
Δ = 2320
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{2320}=\sqrt{16*145}=\sqrt{16}*\sqrt{145}=4\sqrt{145}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-4)-4\sqrt{145}}{2*12}=\frac{4-4\sqrt{145}}{24} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4)+4\sqrt{145}}{2*12}=\frac{4+4\sqrt{145}}{24} $
