Question

4. Simplify the following: (2a2_4a+5)(a2+3a_7)​

Answer 1

Answer:

Solution :-

★ (2a² - 4a + 5) (a² + 3a - 7)

➙ 2a²(a² + 3a - 7) - 4a(a² + 3a - 7) + 5(a² + 3a - 7)

➙ 2a⁴ + 6a³ - 14a² - 4a³ - 12a² + 28a + 5a² + 15a - 35

➙ 2a⁴ + 6a³ - 4a³ - 14a² - 12a² + 5a² + 28a + 15a - 35

➙ 2a⁴ + 2a³ - 21a² + 43a - 35

∴ The answer of this question is 2a⁴ + 2a³ - 21a² + 43a - 35
