The results after simplifying a linear equation are shown. Which result shows exactly one solution?
1 answer:
The only equation from the options given which shows exactly one solution is x = 2
Evaluating the options given :
- x = x ; here, the variable on the right hand side is equal to that on the left hand side, this means there is no value for the variable x.
- x = 2 ; here, the value of varibale x is 2 ; with the equal to sign, it means 2 is the only value which makes x true, hence the only solution.
- 1 = 1 ; Here, there is no variable to which the value of 1 is attached, hence, no solution.
- 0 = 1 ; 0 is not equal to 1.
Therefore, only the equation x =2 gives exactly one solution for the value of x

Answer:
(1.5,0)
(.5,0)
Step-by-step explanation:
Quadratic formula below
We first need to move everything to one side of the equation
4x²-8x+3=0
Then plug everything in
(8±√(-8²-4*4*3))/(2*4)
(8±√16)/8
To calculate the ± we need to do when where it's adding and then negative
we have
(8+4)/8=3/2
and hten
(8-4)/8=1/2
Answer:
-2
