Question

y) 9(x +2)² - 6(x + 2) + 1 factorise it plz​

Answer 1

Answer:

9(x +2)² - 6(x + 2) + 1 = 9x² + 30x +  23

Step-by-step explanation:

Formula: (a +b) = a² + 2ab + b²

9(x +2)² - 6(x + 2) + 1

= 9 [x² + 2 (x)(2) + 2²] - 6(x+2) + 1

= 9 [x² + 4x + 4] - 6x - 12 + 1

= 9x² + 36x + 36 - 6x - 12 + 1

Rearrange similar terms

= 9x² + 36x  - 6x + 36- 12 + 1

= 9x² + 30x + 36- 13

= 9x² + 30x +  23

9(x +2)² - 6(x + 2) + 1 = 9x² + 30x +  23
