reposting this because it′s not yet solved
correctly. I criticize that most of you people
do not test if your solutions fit the given
equations in many cases
x^2 +1−(√(x^3 +x))=6x
please determine
(1) how many real solutions
(2) how many complex solutions
we can expect
(3) solve it
(4) test your solutions
A man gave $5,720.00 to be shared among
his son and three daughters. If each of
the daughter′s share is (3/4) of the son′s share,
how much did the son receive?
In my textbook its written:
In applying the nth−term test we
can see that:
Σ_(n=1) ^∞ (−1)^(n+1) diverges because
lim_(n→∞) (−1)^(n+1) does not exist.
But then why Σ_(n=1) ^∞ (−1)^(n+1) (1/n^2 ) , Σ_(n=1) ^∞ (−1)^(n+1) (1/(ln(n)))
converges ?
5y^2 +2axy+b=0
ay^2 +2bx+5c=0
(5x+3a)y^2 +(4ax^2 )y−bx−5c=0
5y^2 −x(5x+2a)y−ax^3 −3b=0
Please solve simultaneously
for x and y such that all four
equations are obeyed.
y=x^5 +ax^4 +bx^3 +cx^2 +dx+e
If we let x=t+h
can we find h in terms of a,b,c,d,e
such that
y=(t+R)(t^2 +pt+q)(t^2 +s)
this means two roots are of
opposite sign, of course its
possible by shifting the curve
along x, but can we find the
shift h ?
