Question

factorise 9x^2+6x+1-25y^2​

Answer 1

Answer:

hope this help ful for you

Step-by-step explanation:

* 9x^2+6x+1-25y^2

* (3x)^2+2*3x*1+(1)^2-(5y)^2

* (3x+1)^2-(5y)^2

* {(3x+1)+5y}(3x+1)-5y}

* (3x+5y+1)(3x-5y+1)

Answer 2

Answer:

9x^2+ 6x+1-25y^2

=(3x)^2+ 2*3x*1+(1)^2-(5y)^2

=(3x+1^2)-(5y)^2

∴(a^2-b^2=(a+b)(a-b))

=(3x+1+5y)(3x+1-5y)
