Answer 1

Required Answer:-

Given:

• P = x² - 2x + 3
• Q = x² - 5

To find:

• The value of PQ.

Solution:

PQ

= (x² - 2x + 3)(x² - 5)

= x²(x² - 2x + 3) - 5(x² - 2x + 3)

= x⁴ - 2x³ + 3x² - 5x² + 10x - 15

= x⁴ - 2x³ - 2x² + 10x - 15

Hence, Option D is our required answer.

Answer:

• PQ = x⁴ - 2x³ - 2x² + 10x - 15
