Question

12xy(9x^2-16^2)+4xy(3x+4y)

Answer 1

I have gave you hint in the picture to complete answer

Step-by-step explanation:

a^2-b^2 =(a-b)(a+b)

Answer 2

$\huge\mathtt\pink{Incorrect \ Question}$

$12xy(9x^{2} -16^2)+4xy(3x+4y)$

$\huge\mathtt\pink{Correct\ Question}$

$12xy(9x^{2} -16y^{2} )4xy(3x+4y)</p><p>$

━━━━━━━━━━━━━━━

$\frac{12xy(9x2-16y2)}{4xy(3x+4y)}$

$</h2><h2> \frac{12xy(3x+4y)(3x-4y)}{4xy(3x+4y)}$

$\frac{12xy(3x+4y)(3x-4y)}{4xy(3x+4y)} </h2><h2>$

$\frac{(12xy}{4xy} (3x-4y)$

$3(3x-4y)$

$9x-12y$

━━━━━━━━━━━━━━━

Therefore, the answer is 9x-12y.

Hope you find it useful.
