What are the zeros of the polynomial function f(x) = x3 + 2x2 − 24x?

Alik [6]

You may notice that all of the terms have a common factor: $x$ . So, let's take the $x$ out of all the terms. This gives us:

$x(x^2 + 2x - 24) = 0$

Using the Zero Product Property, we can say that both $x = 0$ and $x^2 + 2x - 24 = 0$ .

Let's solve both. $x = 0$ is obvious, but we still need to solve our other term:

$x^2 + 2x - 24 = 0$

Set up

$(x + 6)(x - 4) = 0$

Factor

$x = -6, 4$

Apply the Zero Product Property

Our answer is x = -6, 0, 4.

A right triangle has a hypotenuse with a length of 130 cm. One leg has a length of 100 cm. What is the length of the other leg o

saveliy_v [14]

Answer:

B. √6900

Step-by-step explanation:

The square length of hypotenuse is equal to sum of square length of two legs let x represent the other leg

130^2 = 100^2 + x^2

16900 = 10000 + x^2 subtract 10000 from both sides

6900 = x^2 find the root for both sides

x = √6900
