In betting terms 1 denotes the home team, 2 denotes the away side and X represents the draw.
So 1X means the home side to win or the match to end as a draw. X2 means a draw or the away side to win.
This is also referred to as the "Double Chance" market in the betting markets itself.
Example:
Manchester United v Arsenal
1X = Manchester United to win or draw (This is the same as backing Manchester United on the Double Chance)
X2 = Arsenal to win or draw (This is the same as backing Arsenal on the Double Chance)
N.B. You can also view 1X as laying the away side and X2 as laying the home side.
Simplifying x2 + -2x + -63 Reorder the terms: -63 + -2x + x2 Factor a trinomial. (-7 + -1x)(9 + -1x) Final result: (-7 + -1x)(9 + -1x)
x2 + 1x - 30 = (x + 6) (x - 5)
0.5 x2+C
Since x by itself is the same as 1x, the expression can be re-written as 1x+2x Then, ignore the x's and simply add the numbers to obtain 1x+2x=3x 3x is your answer.
The antiderivative of x2 + x is 1/3x3 + 1/2x2 + C.
the opposite of x or -x or -1x
9-1x=79-x=79-7=x2=xx=2
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
x = 4 or x = -5
the way to do it is X2 - Bsqaure - 1x then divide by 234.5 then you will have your answer. Good day :)
x6 + 3x4 - x2 - 3 = 0(x6 + 3x4) - (x2 + 3) = 0x4(x2 + 3) - (x2 + 3) = 0(x2 + 3)(x4 - 1) = 0(x2 + 3)[(x2)2 - 12] = 0(x2 + 3)(x2 + 1)(x2 - 1) = 0(x2 + 3)(x2 + 1)(x + 1)(x - 1) = 0x2 + 3 = 0 or x2 + 1 = 0 or x + 1 = 0 or x - 1 = 0x2 + 3 = 0x2 = -3x = ±√-3 = ±i√3 ≈ ±1.7ix2 + 1 = 0x2 = -1x = ±√-1 = ±i√1 ≈ ±ix + 1 = 0x = -1x - 1 = 0x = 1The solutions are x = ±1, ±i, ±1.7i.
