Question

please <br />answer of this question x^2-y^2+6y-9 factories​

Answer 1

Answer:

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

Step-by-step explanation:

x² - y² + 6y - 9

= x² - (y² - 6y + 9)

Using identity (a - b)² = a² - 2ab + b². Here a = y and b = 3

= x² - (y - 3)²

Using identity a² - b² = (a + b)(a - b). Here a = x and b = y - 3

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

Hope this helps! :)
