Question

please help me solve!...differentiate y=(3x+1)^2

Answer 1

use chain rule

Answer 2

or simplify the equation and than solve individually...

Answer 3

here's a hint (i'll give a demo)

derivative of \[(3x+2)^3 = 3(3x+2)^2 \times 3 \implies 9(3x+2)^2\]
does that help?

Answer 4

ya that does help...so either chain rule of simplifying will work?

Answer 5

i got 6(3x+1) is that right??

Answer 6

y=(3x+1)^2 = 9x2 + 6x + 1

and differentiate now..

so y` = 18x + 6...

is that ur answer ??

Answer 7

ya..is it terribly wrong?

Answer 8

we got the same dude... @mathdummy4 ...
