Question

x2+y2+2xy+8x+8y+16 factories it for class 9 using identiy​

Answer 1

Answer:

(x + y + 4)(x + y + 4).

Step-by-step explanation:

x2 + y2+2xy + 8x + 8y+16

= (x + y)^2 + 8(x + y) + 16

Let x + y = Z , so we have:

Z^2 + 8Z + 16

= (Z + 4)(Z + 4)

So substituting back for Z:

the original expression = (x + y + 4)(x + y + 4).
