Question

\[\frac{a^4-b^2}{a-b}\]

Answer 1

\[\\frac{\(a^\2\-b)\(a^\2\+b)\}\{a-b}\]
i factor the numerator but i don't know what you want to do with this expression

Answer 2

\[\frac{a^4-b^2}{a-b}=?\]
a)a^2+b^2
b) (a+b)(a^2-b^2)
c)(a+b)(a^2+b^2)

Answer 3

let's try multiplying the conjugate of the bottom to top and bottom

Answer 4

\[\frac{(a^2-b)(a^2+b)}{a-b} \cdot \frac{a+b}{a+b}=\frac{(a^2-b)(a^2+b)(a+b)}{a^2-b^2}\]
nope we can't simplify to anythose

Answer 5

if a=2 and b=3
we have
\[\frac{2^4-3^2}{2-3}=-7\]

\[2^2+3^2=13\]

\[(2+3)(2^2-3^2)=5(4-9)=5(-5)=-25\]
\[(2+3)(2^2+3^2)=5(4+9)=5(13)=65\]

Answer 6

see we don;t get the same for any of them

Answer 7

oh sorry myininaya the question was wrong it is saying the question as a^-b^4/a-b but it was given in the question a^-b^2/a-b ...... so don't waste ur time because of this question thanks again

Answer 8

It's amazing what biological computers can do.
