Add:  <span>(−x^3 + 26x^2 − 7x − 13) + (6x^4 − x^3 +8x + 27)

You may find it easier to write these one above the other:

</span><span>             (−x^3 + 26x^2 − 7x − 13)
+ (6x^4 − x^3               +8x + 27)
-------------------------------------------
 6x^4    -2x^3  + 26x^2   +x   + 14   (answer)

Please note:  You should use " ^ " to indicate exponentation.
</span><span>6x4 −2x3 + 26x2 +x + 14     NO
</span><span>6x4 −2x^3 + 26x^2 +x + 14    YES

According to the Rational Root Theorem, which number is a potential root of f(x) = 9x8 + 9x6 – 12x + 7?
notsponge [240]

<u>Answer-</u>

\boxed{\boxed{\frac{7}{3}}}

<u>Solution-</u>

Rational Root Theorem-

f(x)=a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+.......+a_1x+a_0\ \ \ and\ a_n\neq 0

All the potential rational roots are,

=\pm (\dfrac{\text{factors of}\ a_0}{\text{factors of}\ a_n})

The given polynomial is,

f(x) = 9x^8 + 9x^6-12x + 7

Here,

a_n=9,\ a_0=7\\\\\text{factors of}\ 9=1,3,9\\\\\text{factors of}\ 7=1,7

The potential rational roots are,

=\pm \frac{1}{1},\pm \frac{1}{3}, \pm \frac{1}{9}, \pm \frac{7}{1}, \pm \frac{7}{3}, \pm \frac{7}{9}

=\pm 1,\pm \frac{1}{3}, \pm \frac{1}{9}, \pm 7, \pm \frac{7}{3}, \pm \frac{7}{9}

From, the given options only \frac{7}{3} satisfies.
