Answer 1

1) (6x^2 + 5)(6x^2 - 5)
2) (3x - 2)(2x - 3)
3) (x - 3)(x - 4)

a) 8x^2/3y ÷ 24x/27xy
= 8x^2/3y × 27xy/24x
= 3xy
b) (3x - 6)/(x^2 - 5x + 6)
= (3x -6)/ (x - 3)(x - 2)
= 3 (x - 2)/(x - 3)(x - 2)
= 3/(x - 3)

Answer 2

1) 36x⁴ - 25
= (6x² - 5)(6x² + 5)
2) 6x² - 13x + 6
= (3x - 2)(2x - 3)
3) x² - 7x + 12
= (x - 3)(x - 4)
a) {(8x²)/3y} ÷ {24x/27xy}
={(8x.x)/3y} × {27xy/24x}
={x/1} × {9x/3}
=9x²/3
= 3x²
b) (3x-6)/(x² - 5x + 6)
= 3(x - 2)
---------------
(x - 2)(x - 3)
= 3 / (x - 3)
