1) 4x² + 9 - 12x - 8x + 12
= 4x² - 20x + 21
=4x² - 6x - 14x + 21 doing middle term
= 2x(2x - 3)- 7(2x - 3)
= (2x - 7)(2x - 3) answer
2) 16a² - 40ab + 25b²
= (4a)² - 2× 4a×5b +(5b)² {(a - b)² = a² - 2ab +b² }
= (4a - 5b)² answer
= 4x² - 20x + 21
=4x² - 6x - 14x + 21 doing middle term
= 2x(2x - 3)- 7(2x - 3)
= (2x - 7)(2x - 3) answer
2) 16a² - 40ab + 25b²
= (4a)² - 2× 4a×5b +(5b)² {(a - b)² = a² - 2ab +b² }
= (4a - 5b)² answer
