Solution

factor

3 b^{4} - 9 b^{2}

Solution

3 b^{2} (b^{2} - 3)

Solution steps

3 b^{4} - 9 b^{2}

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

b^{4} = b^{2} b^{2}

= 3 b^{2} b^{2} - 9 b^{2}

Rewrite

9

as

3 \cdot 3

= 3 b^{2} b^{2} - 3 \cdot 3 b^{2}

Factor out common term

3 b^{2}

= 3 b^{2} (b^{2} - 3)
