(9x + 4) * 2x^2

1. Regroup the terms.
2x^2(9x + 4)

2. Expand by distributing the terms.
2x^2 * 9x + 2x^2 * 4

3. Take out the constants.
(2 * 9)x^2x + 2x^2 * 4

4. Simplify 2 * 9 to 18.
18x^2x + 2x^2 * 4

5. Use this product rule: x^ax^b = x^a+b.
18x^2+1 + 2x^2 * 4

6. Simplify 2 + 1 to 3.
18x^3 + 2x^2 * 4

7. Simplify 2x^2 * 4 to 8x^2.
18x^3 + 8x^2

Therefore your answer is:

18x^3 + 8x^2
