Question

y =x2+x3+2x/x. differentiate this equation with respect to x
​

Answer 1

Answer:

$dy \div dx \: = 2x + 3x^{2}$

Explanation:

To get the answer you have to differentiate each part separately. I hope, you know the rules of differentiation.

dy/dx = d/dx(x²) + d/dx(x³) + d/dx(2x/x)

= d/dx(x²) + d/dx(x³) + d/dx(2)

= 2x + 3x²

[N. B-- Differentiation of any constant is zero)

I've given the rule needed in this in the above photo.

Answer 2

Answer:

not sure if it's correct so can somebody check it??
