It is a root of the polynomial if it causes the equation to equal 0.

Let's try each number.

Substituting -3 for x...

(-3)³ - 4(-3)² -11(-3) + 30

-27 - 36 + 33 + 30

0

Therefore, a. -3 is a root to our polynomial.

You could try the rest, but I won't waste time with it. None of the others are roots, and it's multiple choice which means usually just one answer.

How can you represent all of the solutions to systems of inequalities?​
Dimas [21]

Answer:A closed, or shaded, circle is used to represent the inequalities greater than or equal to (≥) or less than or equal to (≤) . The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.Step 1: Line up the equations so that the variables are lined up vertically. Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same. Step 3: Subtract the two equations. Step 4: Solve the one variable system.

hope this helps have a great night ❤️❤️❤️
