Question

(3x²–5x-3)(x²–5x+6) = ?
​

Answer 1

Answer:

3x4-20x3+40x2-15x-18

Answer 2

Solution :-

→ (3x²–5x-3)(x²–5x+6)

→ 3x²(x² - 5x + 6) - 5x(x² - 5x + 6) - 3(x² - 5x + 6)

→ 3x² * x² + 3x² * (-5x) + 3x² * 6 - 5x * x² - 5x * (-5x) - 5x * 6 - 3 * x² - 3 * (-5x) - 3 * 6

→ 3x⁴ - 15x³ + 18x² - 5x³ + 25x² - 30x - 3x² + 15x - 18

→ 3x⁴ - 20x³ + 40x² - 15x - 18 (Ans.)
