Question

[x+3)+6=[x+2] [x-2] check whether it is a quadratic equation​

Answer 1

$(x+3)+6 = (x+2)(x-2)$

$\implies x + 3 + 6 = x^{2} - 2^{2}$

$\implies x + 9 = x^{2} - 4$

$\implies 0 = x^{2} - 4 - x - 9$

$\implies x^{2} - x - 13 = 0$

$Degree \:of \: above \:equation \:is \: 2$

Therefore.,

$(x+3)+6 = (x+2)(x-2) \:is \\\green {a \: Quadratic \:equation .}$
