The equation is - =
Solution
<u>Step 1:</u>
Take square on both sides, we get
3x - 2 -2 = x +2
<u>Step 2:</u>
Subtract 3x - 2 from both sides, we get
-2
<u>Step 3:</u>
Again, square on both sides in order to get rid of the square root from the above equation, we get
Now we have to simplify it,
<u>Step 4:</u>
Now we have to solve this quadratic equation, in order to get the solution.
We get x = 2 and x = -2, When we verifying solution in the original given equation, the solution does not satisfy the equation.
Reason: We get negative number in the square root.
Therefore, it has no Roots.
<em>Answer: b) No roots</em>
Step-by-step explanation:
100% = 96
1% = 100%/100 = 96/100 = 0.96
the temperature changed by 96 - 71 = 25.
how many % are these 25 ?
we check how often 1% fits into 25.
that is done by division :
25 / 0.96 = 26.04166667 ≈ 26%
Answer:
This equation has zero solutions.
Step-by-step explanation:
This equation has zero solutions because 2 is not equal to zero.
