Answer 1

Answer:

${(x + 2)}^{3} = {x}^{2} - 4 \\ {x}^{3} + 8 + 6x(x + 2) = {x}^{2} - 4 \\ {x}^{3} + 8 + 6 {x}^{2} + 12x - {x}^{2} + 4 = 0 \\ {x}^{3} + 5 {x}^{2} + 12 {x}^{2} + 12 = 0 \\ hence \: the \: given \: equation \: is \: not \: of \: the \: form \: \\ a{x}^{2} + bx + c$

The given equation is not quadratic but is cubic polynomial.
