Question

(2x+1)(2x–1)=(4x+3)(x–5),Examine whether the given equation are quadratic equations or not.

Answer 1

Answer :

Given that,

$(2x + 1)(2x - 1) = (4x + 3)(x - 5) \\ \\ \implies4 {x}^{2} - 1 = 4 {x}^{2} - 17x - 15 \\ \\ \implies17x + 14 = 0$

Here, the variable "x" in the given equation having highest power as 1 and thus the equation is not a quadratic one.
