Question

Hmmmmmmmmmmmmmmmmmmmmmmm (5 & 6)

Answer 1

Verified answer

5) (i) 14x² - 23x + 8
= 14x² - 16x - 7x + 8
= 2x(7x - 8) - 1(7x - 8)
= (7x - 8)(2x - 1)

5) (ii) 12x² - x - 35
= 12x² + 20x - 21x - 35
= 4x(3x + 5) - 7(3x + 5)
= (3x + 5)(4x - 7)

6) (i) 6x² + 11x - 10
= 6x² + 15x - 4x - 10
= 3x(2x + 5) - 2(2x + 5)
= (2x + 5)(3x - 2)

6) (ii) 5 - 4x - 12x²
= 5 + 6x - 10x - 12x²
= 1(5 + 6x) - 2x(5 + 6x)
= (5 + 6x)(1 - 2x)
