Answer:

Step-by-step explanation:
Hi there,
The correct quotient is first answer choice.
Cheers.
(1/x) - (2x/(1+x^2)) = 0
Multiply by x(x^2+1)
1(x^2+1)+(−2x)(x)=0x(x2+1)
−x^2+1=0(Simplify both sides of the equation)
−x^2+1−1=0−1(Subtract 1 from both sides)
−x^2=−1
−x^2−1=−1−1(Divide both sides by -1)
x^2=1
x=ñ1(Take square root)
x=1 or x=−1
250x⁴ + 128x
2x(125x³) + 2x(64)
2x(125x³ + 64)
2x(125x³ + 100x² - 100x² + 80x - 80x - 64)
2x(125x³ + 100x² + 80x - 100x² - 80x - 64)
2x(5x(25x²) + 5x(20x) + 5x(16) - 4(25x²) - 4(20x) - 4(16))
2x(5x(25x² + 20x + 16) - 4(25x² + 20x + 16))
2x(5x - 4)(25x² + 20x + 16)
