Question

factorise 9x^2+24x+16 using identity a^2+2ab+b^2=(a+b)^2​

Answer 1

Answer:

$= 9 {x}^{2} + 24x + 16 \\ = 9x {}^{2} + 12x + 12x + 16 \\ = 3x(3x + 4) + 4(3x + 4) \\ = (3x + 4)(3x + 4).$

Answer 2

Answer:

(3x+4)²

Step-by-step explanation:

9x² + 24 + 16

=(3x)² + 2×(3x)×(4) + (4)

=(3x+4)²

=(3x+4) (3x+4)
