-8
No because: 8+3x=x+11+2x (rewrite equation) 8+3x=11+3x (combine like terms) 8=11 (subtract 3x from both sides) This is obviously a false statement, so there is no solution or answer to the equation.
The discriminant is -11.
x^2 + 3x + 7 = 6x + 18 x^2 - 3x - 11 = 0
According to my calculations, yes. 2x+8=3x+11 -8 2x=3x+3 -2x 0=x+3 -3 -3=x
