Factoriser :
- O(x) = (4x + 3)² - 2(4x + 3)(x + 2)
- P(x) = 4x² + 4x + 1 + (2x + 1)(x - 2)
- Q(x) = 49 - (x + 2)²
- R(x) = x² - 25 + 2 (x - 5) (x + 3)

O(x) = (4x+3)² -2(4x+3)(x+2)
(4x+3)(4x+3-2(x+2)
(4x+3)(4x+3-2x-4)
(4x+3)(2x -1)

P(x) 4x² +4x +1 +(2x +1)(x-2)
P(x) (2x +1)(2x+1) 
P(x) (2x+1) +(2x+1+x+2)
P(x) (2x+1)(3x +3)

Q(x) 49-(x+2)²
