Answer:
A
Step-by-step explanation:
that's the right answer
The greatest common factor in this expression is 3x^4. Let's take it out:
3x^4(u^4 - 1)
u^4 - 1 is a difference of two squares and can be factored further:
3x^4(u^2 + 1)(u^2 - 1)
u^2 - 1 is also a difference of two squares:
3x^4(u^2 + 1)(u + 1)(u - 1)
Answer: 2 5/7
Step-by-step explanation:
5(x-4) + 3x - 9x = 6 - (2x +5) + 8x
5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x
-x - 20 = 6x - 1
-20 = 7x - 1
-19 = 7x
X = 2 and 5/7
