2) 4xy
3) 12x
4) 24
5) 44y
Answer:
Option 2 and 3
Step-by-step explanation:
Given : Expression
To find : Which term can be used in the blank of expression so the greatest common factor of the resulting polynomial is 2x ?
Solution :
From the following options first we have to determine that it contain 2x.
1) 2- x is missing
2) 4xy - 2x is present
So,
3) 12x - 2x is present
So,
4) 24 - x is missing
5) 44y - x is missing
Therefore, The required terms are 4xy and 12x.
So option 2 and 3 is correct.
Answer:
2) 4xy
3) 12x
Step-by-step explanation:
You can figure this out by seeing which answer can have a 2x factored out of it.
4xy = 2x(2y)
12x = 2x(6)
The other answers dont have an x in it so you cant factor out a 2x from them.
Answer:
see below
Step-by-step explanation:
sqrt( -6) * sqrt(-24)
We know that sqrt(a b) = sqrt(a) sqrt(b)
sqrt(6) sqrt(-1) * sqrt(24) sqrt(-1)
We know that sqrt(-1) = i
sqrt(6) i * sqrt(24) i
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(6*24) i*i
sqrt(144) i^2
12 i^2
We know that i^2 = -1
12 (-1)
-12
