You can use the Ruffini's rule. The answer using this method is,

And you can see that the multiplicity of the zero x=-4 is 2, and the multiplicity of the zero x=+3 is 1.
Answer: Base numbers are the number of units, or numbers, we use in our counting system, also called a number system. The most common base number is ten because the digits 0-9 are used in the number system. In other words, whenever we want to tell a number to someone we don't use any numbers besides 0-9. If it was a base-5 number system we would only use five different digits, like 0-4.
Step-by-step explanation:
X= 8.29 or 8.3
you have to use the pythagorean theorem (a^2 +b^2=c^2) remember c is the hypotenuse and the hypotenuse is always across from your triangles right angle
