Question

6. Is(x+1)(x+3) = (x-1)(x-4) forms an quadratic equation.​

Answer 1

Step-by-step explanation:

$(x + 1)(x + 3) = (x - 1)(x - 4) \\ x {}^{2} + 3x + x + 3 = {x}^{2} - 4x - x - 4 \\ x {}^{2} + 4x + 3 = {x}^{2} - 5x - 4 \\ {x}^{2} + 4x + 3 - {x}^{2} + 5x + 4 = 0 \\ 9x + 7 = 0$

This is not quadratic equation
