Question

se p(X)= x4-6x³+15x²-18 +10 e q (x) = x+3 deteremine p(x) . Q(x)

Answer 1

p(x) = x^4 - 6x³ + 15x² - 18x + 10
q(x) = x + 3

(x^4 - 6x³ + 15x² - 18x + 10) . (x + 3)
(x^4 . x) - (6x³ . x) + (15x² . x) - (18x . x) + (10 . x) + (x^4 . 3) - (6x³ . 3) + (15x² . 3) - (18x . 3) + (10 . 3)
x^5 - 6x^4 + 15x³ - 18x² + 10x + 3x^4 - 18x³ + 45x² - 54x + 30
x^5 - 6x^4 + 3x^4 + 15x³ - 18x³ - 18x² + 45x² + 10x - 54x + 30
x^5 - 3x^4 - 3x³ + 27x² - 44x + 30
