Answer:
x = 1/2
Step-by-step explanation:
First, let's put the statement into words:
6 * x^2 + 5x = 4
Now, we can see which values work in this equation.
-4/3 doesn't work
1/2 works!
-3/4 doesn't work
2 doesn't work.
Answer: 
Step-by-step explanation:
So the ^ symbol represents a square, or cube.
Answer:
The correct answer is last option
2n + m√n - nm
Step-by-step explanation:
It is given an expression,
4√n² + √m²n - √4n² - √mn²
<u>To simplify the expression</u>
4√n² + √m²n - √4n² - √mn² = 4n + m√n -2n -nm
= 4n - 2n + m√n - n√m
= 2n + m√n - n√m
Therefore the correct answer is last option
