Answer 1

Step-by-step explanation:

Multiply the first terms in the underlined bracket one by one with the 2nd bracket....

(x²+3x-1) × (x²-3x+1)

x² (x²-3x+1) +3x (x²-3x+1) +2 (x²-3x+1)

We get,

(Underlined terms are common terms )

x⁴ - 3x³ + x² + 3x³ - 9x² + 3x + 2x² - 6x + 2

x⁴ + x² - 9x² + 3x + 2x² - 6x + 2

x⁴ - 6x² + 3x - 6x + 2

x⁴ - 6x² - 3x + 2

Adding and subtracting the common terms...

Therefore,

x⁴ - 6x² - 3x + 2

Hope you understood!!!
