Question

4. Roots of (x+2)^2 =0 are​

Answer 1

Answer:

$\implies \: \sqrt{(x + 2) ^{2} } = 0 \\ \\ \implies \: \sqrt{x ^{2} + 4 } = 0 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: .... \sqrt{x ^{2} } = x \: and \: \sqrt{4} = 2\\ \implies \: x + 2 = 0 \\ \\ \huge \implies \: x = - 2$
