Question

Factorize 9x square - y square using a square -b square formula​

Answer 1

Answer:

(9x)^2 - y^2

To do this we have to apply the formula a^2 - b^2

=(a+b) (a-b)

Step-by-step explanation:

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

=(3x+y) (3x-y)

Is the answer

Answer 2

Step-by-step explanation:

Factorize : 9x² - y²

Applied Formula = a²- b² = (a + b ) (a - b)

9x²- 1 y² :

= (3x)²– (y)² [ (3x)² = 9x² ]

= (3x+y) (3x–y)
