When you compare it to a regular factorisation question (e.g. factorise ax^2 + bx + c), look at how the 1st and 3rd term gets the 2nd term through the cross table method. In the same way for this qns, the x^2 and y^2 terms are able to achieve the xy term

ty but how to do b?
Use the factorisation table method on the right. :)
a b | c
d e | f
_ _ _
g h i
Your three numbers would be placed in g h and i
From there, fill up a b c d e and f in a way where
a x d = g
b x e = h
a x e = f
d x b = c
c + f = i
a b | c
d e | f
_ _ _
g h i
Your three numbers would be placed in g h and i
From there, fill up a b c d e and f in a way where
a x d = g
b x e = h
a x e = f
d x b = c
c + f = i
