10-2 = 1 / 102 = 1/100
x=-1 ^ how do you know?
x = 3.5
A negative minus a positive is a negative. i.e -1-(+1)= -2
x2 - x - 2 = 0(x - 2)(x + 1) = 0x = 2 and -1
1/2 − 1/10 = 2/5
3/5 minus 2/10 is 2/5
Unfortunately, 2 over 2 minus 1 equals 5 over 6 is just a wrong answer! If it is 2 over 2, minus 1, the answer is that it equals zero. If it is 2, over 2 minus 1, the answer is that it equals 2.
three over ten
2 minus 2/5 plus 1/2 minus 4 = -1.9
negative 9 over 2
1/2 minus 3/7 is 1/14
2/5 minus 1/15 is 1/3
2 and 1/3
3/2 minus 1/5 = 1 3/10
3 and 2/5 minus 1 and 1/3 = 2 and 1/15
It is: 4/5 minus 1/2 = 3/10
