Solve Q23 Q24 Q27 Q28 with proper steps

Answer 1

Answer:

23. (2x + 3)(3x - 1)

24. -(x - 1)(7x + 12)

27. (3x + 2)(4x - 3)

28. 6a³(b - 1)(4b + 3)

Step-by-step explanation:

(23)

Given Equation is 6x² + 7x - 3

= 6x² - 2x + 9x - 3

= 2x(3x - 1) + 3(3x + 1)

= (2x + 3)(3x - 1)

(24)

Given Equation is -7x² - 5x + 12

= -(7x² + 5x - 12)

= -(7x² + 12x - 7x - 12)

= -x(7x + 12) - 1(7x + 12)

= -(x - 1)(7x + 12)

(27)

Given Equation is 12x² - x - 6

= 12x² - 9x + 8x - 6

= 3x(4x - 3) + 2(4x - 3)

= (3x + 2)(4x - 3).

(28)

Given Equation is -6a³b - 18a³ + 24a³b²

= 6a³(4b² - b - 3)

= 6a³(4b² + 3b - 4b - 3)

= 6a³[b(4b + 3) - 1(4b + 3)]

= 6a³(b - 1)(4b + 3).

Hope it helps!
