You do the brackets first so 3x8 = 24 - 7 = 17
You then do divide so 34/17 = 2
You then do the multiplication so 2x3= 6
Then you have 1-2-6 = - 7
The order you do it in is BIDMAS
B = brackets
I = indices
D = division
M = multiplication
A = addition
S = subtraction
So the answer is - 7
The probability that four of the five digits are the same is 0.036.
There are 10,000 (10*10*10*10) possible sequences. There are 4C3 ways, 4, of having exactly three digits be the same value. The differing digit can be any of the four positions. There are 10P2 ways, 90 (10*9), to choose the digits of the sequence since we have 10 choices for the digit to be repeated, then 9 more options or the differing digit. The product of the combination arrangements and permutation selection, 4*90, shows there are 360 sequences with three of the same digit. Thus the probability is 360/10,000 or 0.036 or 3.6%.

Answer: No solution
x(5-2)(2-2)=12
x(3)(0)=12
Since its times by 0 the x goes away and it is
0=12
No solution

If you want to divide this by x-3, synth. division would be perfect. Use +3 as your divisor:

-------------------------------
1 -2 1 -1 0 Since the remainder is zero, we know that 3 is a root and (x-3) is a factor. The quotient we can
write using the coefficients shown: {1, -2, 1, -1}:
