yep

Answer 7

I see that it is (x+7y)(x+4y) i just get confused with 2 variables.

Answer 8

another method if u get confused by the existance of both x & y is that u divided the whole stuff by y^2
then u get a quadratic in x/y
u can replace x/y = z
n solve quadratic then in solutn write z again as x/y
