Factors of Polynomial Functions

Write the cubic polynomial in factored form with 
zeros -1, 1, and 4

• (x + 1) (x - 1) (x - 4)

• x³ - 4x² - x + 4

• (x + 1) (x - 1) (x + 4)

• x³ - 4x² - x - 4

Factor and solve:
0=x³+11x²+24x

• x=8,3

• x=-8,-3

• x=-8,-3,0

• x=0, 8, -3

Which standard form function matches the factored form:
y = (x + 1)(x - 3)

• y = x² + x - 3

• y = x - 2

• y = x² - 2x - 2

• y = x² - 2x - 3

Which standard form function matches the factored form: 
y = (x + 1)(x - 1)(x + 4)

• y = x³ - x² - 4x

• y = x³ + 4x² - x - 4

• y = x³ - 4x² + x + 4

• y = x³ + x² - x - 4

x² - 16

• ( x - 4) ( x - 4) 

• ( x - 4) ( x + 4) 

• ( x - 8) ( x + 8) 

3x² - 75

• 3( x + 5 ) ( x - 5 ) 

• 3( x - 5 ) ( x - 5 ) 

• ( x + 5 ) ( x - 5 ) 

Factor f(x)= x³ - 2x²-13x - 10  given that (x - 5) is one factor.

• (x- 5)(x - 1)(x - 2)

• (x - 5)(x + 2)(x - 2)

• (x - 5)(x + 2) (x + 1)

• (x - 5)(2x - 13)

Find all zeros:
ƒ(x) = x(4x - 3)(x + 2)

• x = 0, ¾, 2

• x = 0, -¾, -2

• x = 0, 3, -2

• x = 0, ¾, -2
