QUESTION 4

Use synthetic division to divide.

(4x3 + x2 - 11x + 6) ÷ (x + 2)

4x2 - 5x - 6

4x2 - 7x + 3

4x2 - 2x - 2

4x2 + 5x - 12

4x2 + 7x - 4

4 points   

QUESTION 5

Use the Remainder Theorem and synthetic division to find the function value. Verify your answers using another method.

h(x) = x3 - 6x2 - 5x + 7

h(-8)

-849

-847

-851

-848

-845

Rises to the left, falls to the right

Rises to the right, rises to the left

Falls to the left, rises to the right

Falls to the right

Falls to the left, falls to the right

Explanation / Answer

3) FINDINF ALL THE ZEROS OF

F(X) = X^2-25

FOR THIS LET F(X) = 0

THEREFORE X^2-25 = 0

HENCE X^2 = 25

THEREFORE X = +5 AND -5

THEREFORE OPTION E IS CORRECT
