Heya!!✋✋
Here is your answer.
_____________________________
1. px - 5q + pq -5x
=> px + pq - 5q - 5x
=> p(x + q) -5(q + x)
=> (p-5)(q+x)
2. ( 3a - 1 )²-6a+2
=> 9a²-6a + 1 -6a +2
=> 9a² - 12a + 3
=> 9a² - 9a - 3a + 3
=> 9a( a-1) - 3(a-1)
=> (9a-3) (a-1)
3.a³ + a - 3a² - 3
=> a³ - 3a² + a - 3
=> a²(a-3) + 1(a-3)
=> (a²+1) (a-3)
4. x² + y -xy -x
=> x² - x -xy + y
=> x(x-1) -y ( x-1)
=> (x-1) (x-y)
5. (2x-3)² - 8x +12
=> 4x²- 12x + 9 - 8x + 12
=> 4x² - 20x + 21
=> 4x² - 14x - 6x + 21
=> 2x ( 2x - 7) - 3 ( 2x - 7)
=> ( 2x-7) (2x-3)
6. 3ax - 6ay - 8by + 4bx
=> 3ax + 4bx - 6ay - 8by
=> x( 3a + 4b) -2y (3a + 4b)
=> (x - 2y) (3a + 4b)
===============================
Friend, hope it will help you. :)
