Question

Which of the following is a factor of 2xy + 8y − 8x − 32?

Answer 1

We are given

$2xy+8y-8x-32$

We can write it as

$=2y*x+2y*4-8*x-8*4$

we can see that 2y is in first two terms

and -8 is in last two terms

so, we can factor it out

$=2y(x+4)-8(x+4)$

now, we can see that x+4 is common in both terms

so, we can factor it out

$=(x+4)(2y-8)$

we can see that

x+4 is one of factor of terms

so, option-B..........Answer
