Problem
Reorder the polynomial \(7x^3 - 5x^2 + 9x - 4\) in ascending order.
Solution
Step 1 ：Step 1: Identify the terms in the polynomial, \(7x^3\), \(-5x^2\), \(9x\), and \(-4\).
Step 2 ：Step 2: Reorder the terms based on the exponent of \(x\) in ascending order. The term with the smallest exponent should be first and the term with the largest exponent should be last.
Step 3 ：Step 3: The reordered polynomial is \(-4 + 9x - 5x^2 + 7x^3\).
