Question

use the quotient rule to differentiate this:
\[2x^2-2x+1\div2x^2+2x+1\]

Answer 1

@alanli123 the answer was \[4(2x^2-1)\div(2x^2+2x+1)^2\].
but i dont know how to get it

Answer 2

This is the quotient rule \[(f'(x)g(x)- f(x)g'(x) )/ (g(x))^2\]
\[f(x)= 2x^2-2x+1 \]\[g(x)= 2x^2 +2x+1\]

Answer 3

Use product rule to differentiate each function. k?
