Question

factories 9x^2-16y^2​

Answer 1

Answer:

(3x+4y) (3x-4y)

Step-by-step explanation:

9x² - 16y² = (3x)² - (4y)²

using identity a²-b² = (a+b)(a-b)

we get

(3x)² - (4y)² = (3x+4y) (3x-4y)

Answer 2

Answer:

we have to use the formula (a+b) (a-b) = a^2 -b^2

and in this sum we will use the opposite identity a^2-b^2= (a+b) (a-b)

9x^2 - 16y^2

(3x)^2 -(4y)^2

(3x+4y) (3x-4y)

your final answer (3x+4y) (3x-4y)
