What are the zeros of the function? what are their multiplicities? f(x)=x^4-4x^3+3x^2

Answers

Answer 1

Answer: f ( x ) = x² ( x² - 4 x + 3 ) =
= x² ( x² - 3 x - x + 3 ) =
= x² ( x ( x - 3 ) - ( x - 3 ) ) =
= x² ( x - 3 ) ( x - 1 ) = 0
x² = 0 ⇒ x = 0
x - 3 = 0 ⇒ x = 3
x - 1 = 0 ⇒ x = 1
The zeroes of the function are: x = 0, x = 1 and x = 3.
Answer:
B ) The number 0 is a zero of multiplicity 2; the numbers 1 and 3 are zeroes of the multiplicity 1.

220 miles = 10 gallons

$(220)/(550) ~=~ (10)/(x)$

cross multiply :

220x = 5500

Divide 220 from both sides

$(220x)/(220) ~=~ (5500)/(220)$

x = 25

Check :

$(220)/(550) ~=~ (10)/(25)$

0.4 = 0.4

My answer is correct. It's (D.) 25 gallons of gas :)
