factor 3j^3-9j^2

Solution

factor

3 j^{3} - 9 j^{2}

Solution

3 j^{2} (j - 3)

Solution steps

3 j^{3} - 9 j^{2}

Apply exponent rule:

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

j^{3} = j j^{2}

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

Rewrite

9

as

3 \cdot 3

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

Factor out common term

3 j^{2}

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