Answer:
(3x2 + x + 4) • (x - 1)
————————————
x - 3
Step-by-step explanation:
X + 12 = n
N is 5 more than twelve so add 5 to 12 and you get 17.
Step-by-step explanation:
8x-11=629
8x=629+11
8x=640
x=80
Answer:
f(x) = x³ - 5x² - 9x + 45
Step-by-step explanation:
Given x = a, x = b are the zeros of a polynomial, then
(x - a), (x - b) are the factors and f(x) is the product of the factors.
Here the zeros are x = - 3, x = 3 and x = 5, thus
(x + 3), (x - 3) and (x - 5) are the factors and
f(x) = (x + 3)(x - 3)(x - 5) ← expand the first pair of factors using FOIL
= (x² - 9)(x - 5) ← distribute
= x³ - 5x² - 9x + 45
