Question

check whether the following are quadratic equations.......? (x+1)²=2(x-3) ​

Answer 1

${x}^{2} + 2x + 1 = 2x - 6 \\ {x}^{2} + 2x - 2x + 1 + 6 = 0 \\ {x}^{2} + 0 + 7 = 0 \\ {x}^{2} + 7 \\ \\ \\ hope \: it \: hlps \: \\ \\ \\ \\ \\ \\ \\ \\ plzzzz \: \: folllw \: \: me$

YES HHHHH.....

Answer 2

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

${(x + 1)}^{2} = 2(x - 3) \\ \\ {x}^{2} + 1 + 2x = 2x - 6 \\ \\ {x}^{2} + 1 + 6 + 2x - 2x = 0 \\ \\ {x}^{2} + 7 = 0 \\ \\ since \:it \: is \: in \: form \: of \: a {x}^{2} + bx + c = 0 \\ \\ where \: a = 1 \: ,b = 0 ,\: c = 7 \\ \\ which \: is \: in \: form \: of \: quadratic \: equation.$
