Question

Multiply:
(x^3+y^5)(x^3-y^5)

Answer 1

This of the form (a-b)*(a+b).
(a-b)*(a+b)=a^2-b^2
Here a=x^3 and b=y^5
Can u do nw @Helenshouse?

Answer 2

(x^3-b^5)*(x^3+y^5) ???

Answer 3

x9 - y25

Answer 4

(a-b)*(a+b)=a^2-b^2
(x^3-y^5)*(x^3+y^5)=(x^3)^2-(y^5)^2
Does that make sense

Answer 5

Just multiply exponents?

Answer 6

yes u just have to multiply the exponents
but use the given identity [by ajprincess]

Answer 7

Got it Thank you both.

Answer 8

yw:)
Bt can u plz tell me vat u get as ur final answer?

Answer 9

@Ekaansh it wud be really better if u check the answer u got.

Answer 10

What do you mean?

Answer 11

I mean x^9-y^25 is not the final answer

Answer 12

x^6-y^10

Answer 13

ya that's right:)

Answer 14

I'm just not getting the hang of this......Dividing polynomials is an issue for me as well.

Answer 15

I can not tell when to add or subtract and when to reverse the signs.......

Answer 16

This one for example......Why do we subtract.

Answer 17

I am nt exactly following ur question.
If u hav something in the form (a-b)(a+b)
then it can be written as difference of squares. that is a^2-b^2.
That's a general form.

Following me?
