Question

factorise the following​

Answer 1

Answer:

2) i) (b + y^2) (a^2 + x)

ii) (x^2 + y^2)^2

Answer 2

Step-by-step explanation:

2

(i)

a^2b+a^2y^2+bx+xy^2

=a^2(b+y^2) +X(b+y^2)

=(a^2+X) (b+y^2)

(ii)

x^4+2x^2y^2+y^4

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

it is in the form of

(a+b) ^2= a^2+ 2ab+b^2

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