simplify sqrt(x^4+x^2)

Solution

simplify

x^{4} + x^{2}

Solution

x x^{2} + 1

Solution steps

x^{4} + x^{2}

Factor out common term

x^{2} : x^{2} (x^{2} + 1)

= x^{2} (x^{2} + 1)

Apply radical rule:

ab = a b,

assuming

a \geq 0, b \geq 0

x^{2} (x^{2} + 1) = x^{2} x^{2} + 1

= x^{2} x^{2} + 1

Apply radical rule:

a^{2} = a,

assuming

a \geq 0

x^{2} = x

= x x^{2} + 1
