Answer 1

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

Hope it helps!

Answer 2

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.
