21-(3x-4)(4-3x)=3x+1
We move all terms to the left:
21-(3x-4)(4-3x)-(3x+1)=0
We add all the numbers together, and all the variables
-(3x-4)(-3x+4)-(3x+1)+21=0
We get rid of parentheses
-(3x-4)(-3x+4)-3x-1+21=0
We multiply parentheses ..
-(-9x^2+12x+12x-16)-3x-1+21=0
We add all the numbers together, and all the variables
-(-9x^2+12x+12x-16)-3x+20=0
We get rid of parentheses
9x^2-12x-12x-3x+16+20=0
We add all the numbers together, and all the variables
9x^2-27x+36=0
a = 9; b = -27; c = +36;
Δ = b2-4ac
Δ = -272-4·9·36
Δ = -567
Delta is less than zero, so there is no solution for the equation
