Answer 2

Question :

• (x+1)²=2(x-3)

Given :

• (x+1)²=2(x-3)

To find :

• The value of x=?

Solution :

$\large \green{ \bold{ \underline{ \underline{step \: by \: step \: explaination : }}}}$

$\\ \\ \large\implies \displaystyle \tt \: ({x + 1})^{2} = 2(x + 3)$

$\\ \\ \large\implies \tt \: {x}^{2} + 1 + 2x = 2x - 6$

$\\ \\ \large \implies \tt \: {x}^{2} + 2x + 1 - 2x - 6 = 0$

$\\ \\ \large\implies \tt \: {x}^{2} + \cancel{2x} + 1 - \cancel{2x} - 6 = 0$

$\\ \\ \large \implies \tt \: {x}^{2} + 1 - 6 = 0$

$\\ \\ \implies \large \tt \: \: {x}^{2} - 5 = 0$

$\\ \\ \implies \large \tt \: x = \pm \: 5$

$\\ \\ \implies \large \tt \: x = 5 \: \: an d \: \: x = - 5$

$\large \red \bigstar\boxed{ \underline {\bf{the \: value \: of \: x \: is \: 5 \: and \: - 5}}}$
