Question

Need real answer with solution please i need it quickly. No random answers

Answer 1

If you differentiate each piece with respect to x, you'd get

`(d)/(dx)(x)\cdot y + x \cdot (d)/(dx)(y) + (d)/(dx)(2x)+(d)/(dx)(3x^2)=(d)/(dx)(4)`

which becomes

`1\cdot y + x \cdot (dy)/(dx) + 2+6x^1=0`

which is equivalent to B.

The answer is B.
