Given a quadratic equation
1. the first thing we do when we want to compete the square, is write the coefficient of x as 2 times a number.
In our case the coefficient of x is 10, so we write 10 as 2*5
2. then we write +
and -
to the expression:
Answer:

the news paper
Answer:
Do not reject
Step-by-step explanation:
From the question we are told that
Sample size
Sample size
Sample proportion 1
Sample proportion 2
95% confidence interval
Generally for 95% confidence level
Level of significance
Therefore
Generally the equation for confidence interval between is mathematically given as
Therefore
Confidence interval is
Conclusion
Given the confidence interval has zero
Therefore do not reject
The answer is
C. - (x + 3)(x - 4)
because if you solve this....
- (x + 3)(x - 4)
(-x - 3)(x - 4)
-x^2 +4x - 3x + 12
-x^2 + x + 12
