Multiply by 12 to get rid of the fraction:
Combine the :
You can pull -16 as common factor:
Now do the same for question number 2
Do you also need to factor?
mathhelpforum users, I need your help!
While doing some homework, I got stuck on a few problems.
Find the simplest equivalent expression for each of the following:
4xsquared - 64/12xsquared - 60x + 48
2xsquared - 128/4xsquared - 36x + 32
Please show how you got the answer, so that I can learn from difficulties.
Any help will be appreciated!
Please use parentheses when writing fractions . . .
We have: .(4xsquared - 64) / (12xsquared - 60x + 48)
Factor . . .
The fraction becomes: .
The same routine . . .(2xsquared - 128) / (4xsquared - 36x + 32)
(2xsquared - 128)/(4xsquared - 36x + 32)
2(xsquared - 64)
2(xsquared - 8squared)
2(x - 8)(x + 8)
4xsquared - 36x + 32
4(xsquared - 9x +8)
4(x - 1)(x - 8)
So, (2(x - 8)(x + 8))/(4x(x - 1)(x - 8))
= ((x + 8))/(2(x - 1))
Is this right?
EDIT: Soz, I forgot the parentheses
