What is the coefficient of x3 in a polynomial 6x4 + 3x2 + 8x + 5?

What is the coefficient of x3 in a polynomial 6x4 + 3x2 + 8x + 5? Correct Answer 0

Coefficient is the number which is multiplied with respective variable. In the given polynomial 6x4 + 3x2 + 8x + 5, there is not an expression containing x3. So we can write 6x4+ 3x2+8x+5 as 6x4 + 0x3 + 3x2 + 8x + 5. We can see that 0 is multiplied with expression x3, so coefficient of x3 is 0.
