Question

find d/dx of
7x^2(x-6)

Answer 1

i know answer is 7x^2(x-9) all over 3

Answer 2

i know 7x^2 dx= 7x^3/3 so not sure why it is different now

Answer 3

?

Answer 4

\[\frac{ d }{ dx } 7x ^{2} = 14x\]
\[\frac{ d }{ dx } ( x - 6 ) = 1\]

\[\frac{ d }{ dx } 7x ^{2}( x - 6 ) = 7x ^{2} + ( x - 6 ) (14x) = 21x ^{2} - 84x \]

Answer 5

sorry i want the integral
