Question

factorise 9 X square + 6 X Y + Y square​

Answer 1

Answer:

hii mate...

= 9x^2+6xy+y^2

= 9x^2+3xy+3xy+y^2

= ( 9x^2+3xy)+ (3xy+y^2)

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

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

= (3x+y)^2

Hope it helps u...

Answer 2

Answer:

$9 {x}^{2} + 6xy + {y}^{2} = >$

$9 {x}^{2} + 3xy + 3xy + {y}^{2} = >$

$3x(3x + y) + y(3x + y) = >$

$(3x + y)(3x + y) = >$

${(3x + y)}^{2}$

Hope it helps you.
