Answer:
2x³ - 3x² + 5x + 21
Step-by-step explanation:
Given :
(x² - 3x + 7) * (2x + 3)
⇒ x² * 2x + x² * 3 + (-3x) * 2x + (-3x) * 3 + 7 * 2x + 7 * 3
⇒ 2x³ + 3x² - 6x² - 9x + 14x + 21
⇒ 2x³ - 3x² + 5x + 21

Answer:
Given:
- (x² - 3x + 7) × (2x + 3)
Find:
- Find the answer after multiplying thr equation.
Calculations:
= x² × 2x + x² × 3 + (-3x) × 2x + (-3x) × 3 + 7 × 2x + 7 × 3
= 2x³ + 3x² - 6x² - 9x + 14x + 21
= 2x³ - 3x² + 5x + 21
Therefore, 2x³ - 3x² + 5x + 21 is the required answer.
