What are the zeros of x(x² + 4x  12) ?
Indicate all zeros. A.) 12 B.) 6 C.) 3 D.) 2 E.) 0 F.) 2 G.) 6 H.) 12
To find zeros, set the polynomial equal to zero. Zeros of a polynomial function,
such as f(x) = x(x² + 4x  12), indicate the xintercepts of the function. At the xintercept, y is equal to zero. Remember, f(x) is the y value. x(x² + 4x  12) = 0 {set the polynomial equal to zero} x(x + 6)(x  2) = 0 {factored the trinomial, in parentheses, into two binomials} x = 0 or x + 6 = 0 or x  2 = 0 {set each factor equal to zero} x = 0 or x = 6 or x = 2 {solved each equation for x} B.) 6, E.) 0, and F.) 2 Ask Algebra House Comments are closed.
