What is a zero of a polynomial?

Back

A zero of a polynomial is a value of x that makes the polynomial equal to zero.

Front

Back

You can find the zeros by factoring the equation to get (x - 4)(x + 6) = 0, which gives the zeros x = 4 and x = -6.

Front

Back

The real roots are x = 4 and x = 5.

Front

Back

You can factor it as (k + 2)(k + 5).

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, represented as (0, y).

Front

Back

Set x = 0. The y-intercept is (0, 3).

Front

What is a factor of a polynomial?

Back

A factor of a polynomial is a polynomial that divides the original polynomial without leaving a remainder.

Front

Which is a factor of the equation shown on the graph?

Back

(x - 1) is a factor of the polynomial.

Front

What does it mean for a polynomial to be factored completely?

Back

A polynomial is factored completely when it is expressed as a product of irreducible polynomials.
