factor (x-y)^4-9(x-y)^2

factor

(x - y)^{4} - 9 (x - y)^{2}

(x - y)^{2} (x - y + 3) (x - y - 3)

Solution steps

(x - y)^{4} - 9 (x - y)^{2}

Factor out common term

(x - y)^{2} : (x - y)^{2} ((x - y)^{2} - 9)

= (x - y)^{2} ((x - y)^{2} - 9)

Factor

(x - y)^{2} - 9 : (x - y + 3) (x - y - 3)

= (x - y)^{2} (x - y + 3) (x - y - 3)

\frac{6}{8} - \frac{1}{2}

- \frac{2}{3} + \frac{1}{27}

- (- c - 8.4 d - 6)

3 (2 x)^{2} + 2 (2 x) - 4

(x - 8) (7 x + 4)
