Answer:
The answer to your question is 9. (2x - 3)(3x - 4) 10. (x + 4)²
Step-by-step explanation:
9. 6x² - 17x + 12
-Multiply 6 by 12 and find the prime factors of the result
6 x 12 = 72
72 2
36 2
18 2
9 3
3 3
1
-Find two numbers that added gives -17
-These numbers are -8 and -9
-Substitution
6x² - 9x - 8x + 12
-Factor by grouping
3x(2x - 3) - 4(2x - 3)
(2x - 3)(3x - 4)
10. x² + 8x + 16
-Find two numbers that added gives 8 and multiply gives 16
-These numbers are 4 and 4
-Factor like a perfect square trinomial
(x + 4)²
