What are the zeros of the polynomial function f(x) = x3 + x2 − 20x?

Irina-Kira [14]

$x^3 + x^2 - 20x=0\\
x(x^2+x-20)=0\\
x(x^2+5x-4x-20)=0\\
x(x(x+5)-4(x+5))=0\\
x(x-4)(x+5)=0\\
x=0 \vee x=4 \vee x=-5$

What is the slope of the line below.? With the coordinates (8,8) and (5,5)

yarga [219]

To find slope, use the equation:

(y₂ - y₁)/(x₂ - x₁) = slope

Let:

(8,8) = (x₂, y₂)

(5,5) = (x₁, y₁)

Plug numbers into corresponding areas.

(8 - 5)/(8-5) = 3/3

3/3 = 1

The slope of the line is 1, or 1/1 (rise 1, run 1)

hope this helps
