f ( x ) = 10 x ^{ 4 } + ax ^{ 3 } + bx ^{ 2 } + cx + 3, what is true about p and q ? List the possible rational zeros of f .

Obtain the possible rational zeros of the given polynomial, using the Rational –Zero Theorem.

P ( x ) = 8 x ^{ 3 } + 2 x ^{ 2 } + 4 x +1

Give all the possible rational zeros of f using the rational zero theorem:

f ( x ) = x ^{ 4 } + 3 x ^{ 2 } – 36

f ( x ) = 8 x ^{ 4 } – 2 x ^{ 3 } + x + 15

Use the Rational–Zero Theorem to find rational zeros of g if g ( x ) = x ^{ 3 } – 9 x .

Use an alternate technique to find the rational zeros of g .

Tell whether the given x –value is a zero of the function.

f ( x ) = x ^{ 3 } – 3 x ^{ 2 } + 9 x – 27, x = 3 i

Use synthetic division to decide which of the factors 1, –1, 3 and –3 are zeros of the function:

f ( x ) = x ^{ 3 } + 5 x ^{ 2 } – 9 x – 45

f ( x ) = x ^{ 4 } + 4 x ^{ 3 } + 4 x ^{ 2 } – 4 x – 5
