Question

X square + xy + 8 x + 8 y​

Answer 1

Answer:

$\large\boxed{\sf{(x+y)(x+8)}}$

Step-by-step explanation:

${x}^{2} + xy + 8x + 8y$

We have to factorise this:

For this, take out the common terms

Therefore we get,

$= x(x + y) + 8(x + y) \\ \\ = (x + y)(x + 8)$

Answer 2

x2 + xy +8x + 8y

x(x+y) + 8(x+y)

(x+8)(x+y)=0

x = -8

x=-y

Y=8
