Write the simplest polynomial function for each set of zeros

Zeros = -2, 5, -1

the answer should be y = x^3 - 2x^2  - 13x - 10

Step-by-step explanation:

x = -2 5 -1

x + 2 = 0

x - 5 = 0

x + 1 = 0

f(x) = (x + 2) (x + 1)

x(x) + 2(x) + x(1) + 2(1)

x^2 + 2x + x + 2

x^2 + 3x + 2

f(x) = (x^2 + 3x + 2) ( x - 5)

x^2(x) + 3x(x) + 2(x) + x^2(- 5) + 3x(- 5) + 2(- 5)

x^3 + 3x^2 + 2x - 5x^2 - 15x - 10

x^3 - 2x^2 - 13x - 10

f(x) = x^3 - 2x^2 - 13x - 10

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000
