Question

factorise :
25x²-y²+6y-9



please answer in steps ...
thankyou !!​

Answer 1

Answer:

=25y^2 -(y^2+6y+9)

=(5y)^2 -(y+3)^2

=(5y +y+3)(5y -y-3)

=(6y+3)(4y-3)

Answer 2

Answer:

(5x+y)(5x-y) +3(2y-3)

Step-by-step explanation:

25x² - y² + 6y - 9 = (5x)² - y² + 3(2y - 3)

= (5x+y)(5x-y) +3(2y-3)

*Identity—a²-b²=(a+b)(a-b)*

Hope it helps you:)
