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)
