yan poh ung answer with complete solution
Answer:
1. (x - 4) (2x - 1) -Substitution
2x²-x-8x+4
= 2x²-9x+4
2. (2x + 5) (2x - 5) -Substitution
4x²-10x+10x-25
= 4x²-25
3. (x - 4) (x² + 4x + 16) -Substitution
x³+4x²+16x-4x²-16x-64
= x³-64
4. ( x + 5) (x² - 5x + 25) - Substitution
x³-5x²+25x+5x²-25x+125
= x³+125
