factor 9x^2-15x^4

Solution

factor

9 x^{2} - 15 x^{4}

Solution

3 x^{2} (3 - 5 x^{2})

Solution steps

9 x^{2} - 15 x^{4}

Apply exponent rule:

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

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

= 9 x^{2} - 15 x^{2} x^{2}

Rewrite

9

as

3 \cdot 3

Rewrite

15

as

3 \cdot 5

= 3 \cdot 3 x^{2} - 3 \cdot 5 x^{2} x^{2}

Factor out common term

3 x^{2}

= 3 x^{2} (3 - 5 x^{2})
