Answer:
(x-12) (x+12)
Step-by-step explanation:
If you factor it out since both are perfect squares you would place an x on each side and then find the square root of 144, which is 12 and put a positive and a negative in each parenthesis.
Answer:
The values of a, b and c are:
Step-by-step explanation:
Step 1:
First Confirm the sequence is quadratic by finding the second difference.
Sequence = 
1st difference:
2nd difference:
Step 2:
Just divide the second difference by 2, you will get the value of
.
6 ÷ 2 = 3
So the first term of the nth term is 
Step 3: Next, substitute the number 1 to 5 into 
n = 1,2,3,4,5
3n² = 3,12,27,48,75
Step 4:
Now, take these values (3n²) from the numbers in the original number sequence and work out the nth term of these numbers that form a linear sequence.
n = 1,2,3,4,5
3n² = 3,12,27,48,75
Differences:
1 - 3 = -2
11 - 12 = -1
27 - 27 = 0
49 - 48 = 1
Now the nth term of these differences (-2,-1,0,1) is (n - 1) - 2.
so b = 1, and c = -3
Step 5: Write down your final answer in the form an² + bn + c.
3n² + (n - 1) -2
= 3n² + n - 1 - 2
= 3n² + n - 3
Therefore, the values of a, b and c are:
Step-by-step explanation:
7(x-2)+3 (x+2)=5 (x-6)
- 7x-14+3x+6=5x-30
- 10x-8=5x-30
- 10x-5x=-30+8
- 5x=-22
- x=-22/5
Answer:
The strong nuclear force holds together the quarks and gluons within protons and neutrons. It also holds together the protons and neutrons within the nucleus of the atom.
