Five times a number decreased by eight is at most ten more than twice the number

Allisa [31]

$5n-8 \leq 2n+10 \\ 5n-8+8 \leq 2n+10+8 \\ 5n \leq 2n+18 \\ 5n-2n \leq 2n+18-2n \\ 3n \leq 18 \\ \frac{3n}{3} \leq \frac{18}{3} \\ n \leq 6$

Which product of prime polynomials is equivalent to 3x4 – 81x?

aleksley [76]

3x(x – 3)(x2 + 3x + 9)

and the formula is

a3-b3=(a-b)(a2+ab+b2)

but since here it is 3x4 we put 3x before the formula.
