If a polynomial function f(x) has roots –8, 1, and 6i, what must also be a root of f(x)?

inna [77]

For any polynomial with a complex root, the imaginary part of the complex root always has positive and negaive component. Since one of the roots of this polynomial is 6i, then -6i must also be a root of the function.

What is a reason that we need to be able to use the quadratic formula rather than solving all quadratic equations by graphing?

MArishka [77]

Here are some examples of how the Quadratic Formula works:

Solve x2 + 3x – 4 = 0

This quadratic happens to factor:

x2 + 3x – 4 = (x + 4)(x – 1) = 0

Then, as expected, the solution is x = –4, x = 1.

This is #5 Algebra-Find the value for x I know it’s 11 but how do I get there.

Sergeeva-Olga [200]

Answer:

x = 11

Step-by-step explanation:

the line x + 5 is a mid segment of the triangle and thus is half the length of 3x - 1, that is

x + 5 = $\frac{1}{2}$ (3x - 1)

multiply both sides by 2 to eliminate the fraction

2x + 10 = 3x - 1 ( subtract 3x from both sides )

- x + 10 = - 1 ( subtract 10 from both sides )

- x = - 11 ( multiply both sides by - 1 )

x = 11
