Write a polynomial function in standard form with zeros at −3, −1, and 1.

Annette [7]

Answer:

$f(x) = {x}^{3} + 3 {x}^{2} - x -3$

Step-by-step explanation:

The given polynomial has zeros at:

x=−3, x=−1, and x=1.

This means that:

x+3, x+1, and x-1 are all factors of this polynomial.

The factored form of this polynomial is :

$f(x) = (x + 3)(x + 1)(x - 1)$

We expand the last two factors using difference of two squares.

$f(x) = (x + 3)( {x}^{2} - 1)$

$f(x) = x ( {x}^{2} - 1) + 3( {x}^{2} - 1)$

$f(x) = {x}^{3} - x+ 3 {x}^{2} -3$

$f(x) = {x}^{3} + 3 {x}^{2} - x -3$

This is the standard form because it is now in decreasing powers of x.

Which of the binomials below is a factor of this trinomial?

Elina [12.6K]

STEP-BY-STEP SOLUTION:

= x^2 - 13x + 30

= x^2 - 10x - 3x + 30

= x ( x - 10 ) - 3 ( x - 10 )

= ( x - 10 ) ( x - 3 )

FINAL ANSWER:

Therefore, the answer is:

C. x - 10
