Hey dear!
Here is yr answer.....
1) x² - 3x + 2
=> x² -2x -x + 2
=> x(x-2) -1(x-2)
=> (x-2) (x-1)
_____________________________
2) x² - 5x - 6
=> x²- 6x + x - 6
=> x(x-6) + 1(x-6)
=> (x-6) (x+1)
______________________________
3) x² - 13x + 36
=> x² - 9x - 4x + 36
=> x(x-9) -4(x-9)
=> (x-9) (x-4)
______________________________
4) x² + 5x + 6
=> x² + 3x + 2x + 6
=> x(x+3) + 2(x+3)
=> (x+3) (x+2)
______________________________
5) x² - 22x + 120
=> x² - 12x - 10x + 120
=> x(x-12) -10(x-12)
=> (x-12) (x-10)
______________________________
6) x² + 5x - 36
=> x² + 9x - 4x - 36
=> x(x+9) - 4(x+9)
=> (x+9) (x-4)
______________________________
7) 3x² - 14x + 8
=> 3x² - 12x - 2x + 8
=> 3x(x-4) + 2(x-4)
=> (x-4) (3x+2)
______________________________
8) 2x² - 7x - 15
=> 2x² - 10x + 3x - 15
=> 2x(x-5) + 3(x-5)
=> (x-5) (2x+3)
_____________________________
9) 4x² - 17x - 21
=> 4x² - 21x + 4x - 21
=> x(4x-21) + 1(4x-21)
=> (4x-21) (x+1)
Hope it hlpz...
