Answer is 1/2 ln (x^2+1) + 2 tan ^-1 (x) +c
in order to do this first say (x/x^2+1)+ 2/(x^2+1)
we already know that 1/x^2+1 equal tan^-1 (x)
for the first part you need to say u=x^2+1 and solve it by substitution
I hope this helps..let me know if you need more explanation
Answer:
Step-by-step explanation:
Just because before y there is negative "-" thus youve got to put it before 18. Eventually the answer is -18,not 22

Step-by-step explanation:
D is the answer because 13 goes into 5 twice and 3 Is left over multiply that by two to get 6/10 than that it's equivalent to .6 so it is 2.6
We are technically FOILing this out... with a power of 3.
(x+y)(x+y)(x+y)
So we can first factor out the first two "x+y"s.
, multiplied by the last "x+y".
Coefficients are the number that comes
in front of a variable. In this case, 1 comes in front of
, 3 comes in front of
, 3 comes in front of
, and 1 comes in front of
.
Thus: 1, 3, 3, 1.
