To change a mixed fraction, you'd multiply the number upfront, times the denominator, and then add that product to the numerator
that IS the new numerator, and you keep the denominator
thus $\bf 8\frac{2}{3}\iff \cfrac{8\cdot 3+2}{3}$

Which polynomial is prime?

finlep [7]

we know that

If the only factors a polynomial are $1$ and itself, then that polynomial is prime.

If the polynomial has at least one root (one x-intercept) then the polynomial is not prime

Using a graph tool

case 1)

$x^{3}+ 3x^{2} + 2x+ 6$

see the attached figure N 1

The polynomial has one root-------> the polynomial is not prime

case 2)

$x^{3} + 3x^{2} - 2x - 6$

see the attached figure N 2

The polynomial has three roots-------> the polynomial is not prime

case 3)

$10x^{2}-4x+3x + 6$

$10x^{2} -x + 6$

see the attached figure N 3

The polynomial has zero roots-------> the polynomial is prime

case 4)

$10x^{2}-10x+6x - 6$

$10x^{2} -4x - 6$

see the attached figure N 4

The polynomial has two roots-------> the polynomial is not prime

therefore

the answer is

$10x^{2}-4x+3x + 6$ ------> is prime

Relationship between the values of given digits 6s in 6,600

The 6 on the left side is 10x more than the 6 on the right. This only works if the numbers are next to each other and are the same.
