x^2-3x+2-3x^2+5x+1=
x^2-3x^2-3x+5x+2+1=
-2x^2+2x+3
Answer:
Step-by-step explanation:
integral(x/(1+x^2)^2)dx
=(1/2)integral(2x/(1+x^2)^2)dx
=(1/2)[-1/(1+x^2)] +c
Answer:
It would be E.
Step-by-step explanation:
30,030 can be divided into 10010 and 3. 10010 can be divided into 10 and 1001. 10 can be divided into 2 and 5, while 1001 can be divided into 13 and 77. 77 can divided into 7 and 11. This leads the prime factorization to be E, as it is 2, 3, 5, 7, 11 and 13.
Answer:
x=10 x=-4
Step-by-step explanation:
x^2 +6x = 40
subtract 40 from each side
x^2 +6x -40 = 0
what numbers multiply to -40 and add to 6
-10 *4 = -40 -10 +4 = 6
(x-10) (x+4) = 0
using the zero product property
x-10 = 0 x+4 =0
x=10 x=-4
Answer:
Yes, x and y do have a proportional relationship.
