Question

Check (x + 1)2 = 2(x-3) is quadratic equation or not.​

Answer 1

Answer:

no

Step-by-step explanation:

2x+2=2x-6

2x-2x=-6-2

0=-8

Answer 2

$\huge\sf\underline\pink{Answer}$

$\implies\sf (x \:+\:1)^2 = 2(x\:-\:3)$

$\implies\sf x^2 + 1^2 + 2 \times x \times 1 = 2(x\:-\;3)$

$\implies\sf x^2 + 1 + 2x = 2x - 6$

$\implies\sf x^2 + 1 + 2x - 2x + 6 = 0$

$\implies\sf x^2 + 1 + 6 = 0$

$\implies\sf x^2 + 7 =0$

$\implies\sf x^2 + 0x + 7 = 0$

$\sf since, \: it \: is \: in \; the \: form\: of\; quadratic\: Equation$

$\sf Hence, \; it \; an \; quadratic\; Equation$
