Answer:
In the first equation x=4 or x=-3
In the second equation x=-4 or x=3
Explanation:
The first equation x^2 − x − 12 can be factorized as follows:
x^2-4x+3x-12
x(x-4)+3(x-4)
x-4=0 or x+3=0
x=4 or x=-3
It is noteworthy that -x was rewritten as -4x+3x in order to solve the equation
The second equation x^2 + x − 12 can be factorized as below:
x^2+4x-3x-12
x(x+4)-3(x+4)
x+4=0 or x-3=0
x=-4 or x=3
It is noteworthy that +x was rewritten as 4x-3x in order to solve the equation
It should be noted that the centers and variabilities that should be apparent in the distributions is that as the sample size increases, the variability of each sampling distribution decreases.
<h3>What is a sample size?</h3>
It should be noted that a sample size simply means the number if subjects that are talked into consideration from the entire population.
In this case, the centers and variabilities that should be apparent in the distributions is that as the sample size increases, the variability of each sampling distribution decreases. This was generated from the simulations.
