find required factor: x^2(x^3-1)=(?)(x^3-1)^4(3x^2)

[kewlkkid1]

okay i need help:

Find the required factor:

x^2(x^3-1)=(?)(x^3-1)^4(3x^2)

Write the sum of the terms :

16-5x-x^2/x

3-55x^2-x^4/square root 4

What have you tried? Where is your work?

suppose you were to solve for 'M' from

\(\displaystyle 5^2\cdot (2^3 -1) = M \cdot (2^3-1)^4\cdot (3\cdot 5^2)\)

- Without using calculator.

Write the sum of the terms :

16-5x-x^2/x

3-55x^2-x^4/square root 4

Re: precalculus

ohh i get it u would solve for both sides until u got (M) by itself and work it out from there but how do u deal with all the (x)s in that problem i dont get how u can solve that??

The teacher gave you the problem, but did not teach how ? :shock:

Hi Kid:

Subhotosh hoped that his example with the symbol M would lead you to see that there are similar factors on both sides of the equal sign.

If you see the same factor on both sides, then you can cancel them both by dividing each side of the equation by that factor.

This is how you start to simplify the equation in your first exercise.

Let us know if you don't understand what factors are.
