simplify sqrt(-2x^2)

Solution

simplify

- 2 x^{2}

Solution

2 i x

Solution steps

- 2 x^{2}

Apply radical rule:

- a = - 1 a,

assuming

a \geq 0

- 2 x^{2} = - 1 2 x^{2}

= - 1 2 x^{2}

Apply imaginary number rule:

- 1 = i

= i 2 x^{2}

Apply radical rule:

assuming

a \geq 0, b \geq 0

2 x^{2} = 2 x^{2}

= 2 i x^{2}

Apply radical rule:

assuming

a \geq 0

x^{2} = x

= 2 i x
