Question

divide the following​

Answer 1

Answer:

6) (3x+2) (5x-3)

Step-by-step explanation:

6) = 15x^2+x-6

= 5x (3x+2). -3 (3x+2)

= 15x^2+10x-9x-6

= 5x (3x+2)-3 (3x+2)

= (3x+2) (5x-3)

Answer 2

Answer:

Step-by-step explanation:

4. x² - 4 =(x + 2)(x - 2)

(x² - 4) ÷ (x + 2) = x - 2

10. a³ + b³ = (a + b)(a² - ab + b²)

x³ + 1 = (x + 1)(x² - x + 1)

(x³ + 1) ÷ (x + 1) = x² - x + 1
