I do not undestand why you put: v = x cubed and v´= 1
derivative of x cubed = derivative of (x^3) = 3x^2
Let me know....
hey everyone, so the question is y= -5 over x cubed minus 2 over x + (x+1)
for -5 over x cubed:using quotient rule, let u= 5 v= x cubed u'= 0 v'= 1
y'(x)= x cubed(0) - 5(1) all over (x+1)^2
= 0-5 all over (x+1)^2 ?????
am I on the right track? or am i supposed to include the minus sign somwhere?
