Answer:
-4
Step-by-step explanation:
Step 1: Subtract 7 from both sides.
−2x+7−7=15−7
−2x=8
Step 2: Divide both sides by -2.
−2x
−2
=
8
−2
x=−4
Answer:
The multiplicity of the root is 1
Step-by-step explanation:
Firstly, we need to understand what multiplicity is
By multiplicity, we simply refer to the number of times we have the certain root repeating itself
From the factorization, each of the given roots were only repeated once
That indicates that the given multiplicity is 1
The answer to the question is d
Answer:
Only Ivan
Step-by-step explanation:
First of all - never do what Javier did!! You can’t separate things like that. It’s a violation of math (also it breaks my heart, and you don’t want that!).
Ivan is correct in taking out a factor of 2 from both the top and bottom.
6x+4 = 2(3x+2)
12x+4 = 2(6x+2)
The twos cancel, and you get 3x+2 / 6x+2.
