Answer 2

$\huge{\underline{ Question:}}$

$Is \: \: (x+1)²=2(x-3) \: \: a \: \: Quadratic \: \: equation \: ?$

$\bold {\underline{Note \:: }} \: \: Quadratics \: \: or \: \: quadratic \: \: equations \: \: can \: \: be \: \: defined \: \: as \: \: a \: \\ \: polynomial \: \: equation \: \: of \: \: a \: \: second \: \: degree.$

$The \: \: definite \: \: form \: \: is \: \: ax² + bx + c = 0.$

$\huge\red{\underline{ \underline{Answer :}}}$

${(x + 1)}^{2} = 2(x - 3)$

$\boxed{{(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab}$

${x}^{2} + {1}^{2} + 2(x)(1) = 2x - 6$

${x}^{2} + 1 + 2x = 2x - 6$

${x}^{2} + 2x - 2x = - 6 - 1$

${x}^{2} = - 7$

${x}^{2} + 7 = 0$

$This \: \: equation \: \: is \: \: a \: \: quadratic \: \: equation, as \: \: it \: \: has \: \: a \: \: variable \: \: of \: \: degree \: 2.$
