factor 7x+y-xy-7-z^2+xz^2

factor

7 x + y - x y - 7 - z^{2} + x z^{2}

(- 1 + x) (7 - y + z^{2})

Solution steps

7 x + y - x y - 7 - z^{2} + x z^{2}

Rewrite as

= 7 x + y - x y - 7 \cdot 1 - z^{2} + x z^{2}

Factor out common term

7

= 7 (x - 1) + y - x y - z^{2} + x z^{2}

Factor out common term

y

= 7 (- 1 + x) + y (1 - x) - z^{2} + x z^{2}

Rewrite as

= 7 (- 1 + x) - (- 1 + x) y - z^{2} + x z^{2}

Factor out common term

(- 1 + x)

= (- 1 + x) (7 - y) - z^{2} + x z^{2}

Factor out common term

z^{2}

= (- 1 + x) (7 - y) + z^{2} (- 1 + x)

Factor out common term

(- 1 + x)

= (- 1 + x) (7 - y + z^{2})

\frac{a - 7}{3} = \frac{a + 5}{2} - \frac{7 a - 1}{6}

2 d + 4 = 10 + 5 d

(a^{\frac{1}{n}})^{m}

- 1 - (- 4)
