Question

Factorise the polynomial. (x² - 2x + 3) (x² -2x + 5) – 35​

Answer 1

Answer:

Answer:

x² - 4x³ + 9x² - 16x - 20

Step-by-step explanation:

Given: (x² - 2x + 3)(x² - 2x + 5) - 35

→x²(x² - 2x + 5) - 2x(x² - 2x + 5) + 3(x² - 2x

+5) - 35

→x² - 2x³ + 5x² - 2x³ + 4x² - 10x + 3x² - 6x X

+ 15 - 35

→x-2x³ - 2x³ + 5x² + 4x² + 3x² - 10x - 6x

+ 15 - 35

→x² - 4x³ + 9x² - 16x-20
