Mathematics

Anastaziya [24]2 years ago
6 0

if a > 0, there are two possible solutions:

x^{2} = a\\\sqrt{x^{2} } = \sqrt{a} \\

the square root of a square is the base in absolute value bars

|x| = \sqrt{a}

x = -\sqrt{a} ; x = \sqrt{a}

if a = 0, that means x = 0. anything multiplied by 0 is 0

if a < 0, there are no solutions because anything squared has to be positive
