24+3x^2+2x=5(x-2)(x+2)
We move all terms to the left:
24+3x^2+2x-(5(x-2)(x+2))=0
We use the square of the difference formula
3x^2+x^2+2x+4+24=0
We add all the numbers together, and all the variables
4x^2+2x+28=0
a = 4; b = 2; c = +28;
Δ = b2-4ac
Δ = 22-4·4·28
Δ = -444
Delta is less than zero, so there is no solution for the equation
