If a polynomial function f(x) has roots 0, 4, and 3 + square root 11 , what must also be a root of f(x)?
Galina-37 [17]
3-√11
This function is evidently a quartic - a function with 4 roots. The last root has been found using the quadratic formula however, the answer always comes in pairs because the formula is
{b+√(b^2 - 4ac)}/2a and {b-√(b^2 - 4ac)}/2a. Therefore the other root must be 3-√11

the first term of a arithmetic sequence is 2 and the 4th term is 11, how do I find the sum of the first 50 terms
Rama09 [41]
\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
a_1=2\\
a_4=11\\
n=4
\end{cases}
\\\\\\
a_4=2+(4-1)d\implies 11=2+(4-1)d\implies 11=2+3d
\\\\\\
9=3d\implies \cfrac{9}{3}=d\implies \boxed{3=d}\\\\
-------------------------------\\\\

\bf \textit{now, what's the 50th term anyway?}
\\\\\\
n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
a_1=2\\
n=50\\
d=3
\end{cases}
\\\\\\
a_{50}=2+(50-1)3\implies a_{50}=2+147\implies a_{50}=149\\\\
-------------------------------\\\\

\bf \textit{sum of a finite arithmetic sequence}\\\\
S_n=\cfrac{n}{2}(a_1+a_n)\quad 
\begin{cases}
n=50\\
a_1=2\\
a_{50}=149
\end{cases}\implies S_{50}=\cfrac{50}{2}(2+149)

Resuelve las siguientes ecuaciones en tu cuaderno y realiza la comprobación de
Soloha48 [4]
3x + 2 + 12x = 0
15x + 2 = 0
15x + 2 - 2 = 0 - 2
15x = -2
15x/15 = -2/15
X = -2/15
