factor 9r^4-s^4

factor

9 r^{4} - s^{4}

(3 r^{2} + s^{2}) (3 r^{2} - s^{2})

Solution steps

9 r^{4} - s^{4}

9 r^{4} = (3 r^{2})^{2}

s^{4} = (s^{2})^{2}

= (3 r^{2})^{2} - (s^{2})^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

(3 r^{2})^{2} - (s^{2})^{2} = (3 r^{2} + s^{2}) (3 r^{2} - s^{2})

= (3 r^{2} + s^{2}) (3 r^{2} - s^{2})

(\frac{7}{4} m^{- 2})^{2}

\frac{4 π}{2}

(0.006 q^{2}) + (22) = 80

2 x + 3 = 3 x - 4

(- 1)^{8}
