Answer 1

Step-by-step explanation:

1.

$qr - pr \: + qs - ps$

$r(q - p) + s(q - p)$

$(r + s)(q - p)$

2.

${x}^{2} + y - xy - x$

${x}^{2} - x - xy + y$

$x(x - 1) - y(x - 1)$

3.

$6xy + 6 - 9y - 4x$

$- 4x + 6 + 6xy - 9y$

$2( - 2x + 3) - 3y( - 2x + 3)$

$(2 - 3y)( - 2x + 3)$

4.

${x}^{2} - 2ax - 2ab + bx$

$x(x - 2a) - b(x - 2a)$

$-(x +b)(2a-x)$

5.

$axy + bcxy - az - bcz$

$xy(a + bc) - z(a + bc)$

$(xy - z)(a + bc)$
