SOLVING POLYNOMIAL EQUATIONS USING RATIONAL ROOT THEOREM WORKSHEET

Problem 1 :

Solve the equation

x³ - 5x² - 4x + 20 = 0

Solution

Problem 2 :

f(x) = 3x⁴ - 2x² + 6x - 10

Solution

Problem 3 :

f(x) = x³ - 10x² + 14x - 36

Solution

Problem 4 :

f(x) = x³ + 3x² - x + 8

Solution

Problem 5 :

f(x) = 5 - 7x⁴ + 3x² + x -20

Solution

Problem 6 :

f(x) = x⁴ - 7x³ - 4x² + x - 49

Solution

Problem 7 :

f(x) = 2x⁴ - 5x³ + 8x² + 3x - 5

Solution

Problem 8 :

f(x) = 3x⁴ - 5x³ + 10x + 12

Solution

Problem 9 :

f(x) = 4x⁵ - 2x + 18

Solution

Problem 10 :

f(x) = 5x⁶ - 3x⁴ + 5x³ + 2x² - 15

Solution
