Answer 1

Answer:

you can take common and do it

Step-by-step explanation:

1.

qr - pr \: + qs - psqr−pr+qs−ps

r(q - p) + s(q - p)r(q−p)+s(q−p)

(r + s)(q - p)(r+s)(q−p)

2.

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

2

+y−xy−x

{x}^{2} - x - xy + yx

2

−x−xy+y

x(x - 1) - y(x - 1)x(x−1)−y(x−1)

3.

6xy + 6 - 9y - 4x6xy+6−9y−4x

- 4x + 6 + 6xy - 9y−4x+6+6xy−9y

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

(2 - 3y)( - 2x + 3)(2−3y)(−2x+3)

4.

{x}^{2} - 2ax - 2ab + bxx

2

−2ax−2ab+bx

x(x - 2a) - b(x - 2a)x(x−2a)−b(x−2a)

-(x +b)(2a-x)−(x+b)(2a−x)

5.

axy + bcxy - az - bczaxy+bcxy−az−bcz

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

(xy - z)(a + bc)(xy−z)(a+bc)

Answer 2

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.

$axy + bcxy - az - bcz$

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

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