Question

muliply (x^2 + y^5)(x^2 + -y^5)

Answer 1

distribute

Answer 2

x^4-y^10

Answer 3

if
(a+b)*(c+d) = (x^2 + y^5)(x^2 + -y^5)
a b c d
then
a*c+a*d+b*c+b*d

Answer 4

make it simple by letting

x^2 = a
y^5 = b

so you have:

(a+b)(a-b)

then use distribution method. after getting the answer, substitute the values to a and b.

Answer 5

this is another difference of squares problem

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

Answer 6

didn't catch that lol but my way will still solve it
