Question

(х^15+5)(х^3+2)-10-х^18

Answer 1

${x}^{18} + 5 {x}^{3} + 2 {x}^{15} + 10 - 10 - {x}^{18} = \\ = {x}^{3} (5 + 2 {x}^{12} )$

Answer 2

To simplify the expression, let's start by expanding the given expression:

(х^15 + 5)(х^3 + 2) - 10 - х^18

Expanding the first two terms using the distributive property:

(х^15 * х^3) + (х^15 * 2) + (5 * х^3) + (5 * 2) - 10 - х^18

Now, simplify the terms:

х^18 + 2х^15 + 5х^3 + 10 - 10 - х^18

The х^18 terms cancel out each other:

2х^15 + 5х^3

So the simplified expression is:

2х^15 + 5х^3
