Question

Which is an expression of degree 4 which has a leading coefficient of 9 and a quadratic term withcoefficient of 10.A. 9x* + 2x + 10x?B. 10x* + 2x + 9x?C 10x2 + 9x + 4D. 4 + 9x? + 10x

Answer 1

The given expressions are

`\begin{gathered} 9x^4+2x^3+10x^2 \\ 10x^4+2x^3+9x^2 \\ 10x^2+9x+4 \\ 4+9x^2+10x \end{gathered}`

Between these choices, the first expression is the one which has degree 4, a leading coefficient of 9, and the quadratic term has a coefficient of 10.

Therefore, the right answer is A.
