Answer:

x³ + 2x² - 5x - 6

Step-by-step explanation:

If zeros are x = -3, -1, and 2, then the factors are :

= (x + 3)(x + 1)(x - 2)

= (x² + 4x + 3)(x - 2)

= x³ +  4x² + 3x - 2x² - 8x - 6

= x³ + 2x² - 5x - 6

Which ordered pair is the solution to the system of equations? {x+3y=-12, y= 1/3x-6?
Julli [10]

For this, I'll be using the substitution method. Since y = 1/3x - 6, replace the y variable in the first equation with 1/3x - 6 and solve for x:

x+3(\frac{1}{3}x-6)=-12\\ x+x-18=-12\\ 2x-18=-12\\ 2x=6\\ x=3

Now that we have the value of x, plug it into either equation to solve for y:

3+3y=-12\\ 3y=-15\\ y=-5\\ \\ y=\frac{1}{3}*3-6\\ y=1-6\\ y=-5

<h3><u>In short, the solution to this equation is (3,-5).</u></h3>
