factor sqrt(-4x^2)

Solution

factor

- 4 x^{2}

Solution

2 i x

Solution steps

- 4 x^{2}

Apply radical rule:

- a = - 1 a,

assuming

a \geq 0

- 4 x^{2} = - 1 4 x^{2}

= - 1 4 x^{2}

Apply imaginary number rule:

- 1 = i

= i 4 x^{2}

Apply radical rule:

assuming

a \geq 0, b \geq 0

4 x^{2} = 4 x^{2}

= 4 i x^{2}

4 = 2

= 2 i x^{2}

Apply radical rule:

assuming

a \geq 0

x^{2} = x

= 2 i x
