Subtract 3/2+sqr root 5 - 3/2-sqr root 5
To subtract these two expressions, we need to combine like terms:
(3/2 + sqrt(5)) - (3/2 - sqrt(5))
First distribute the negative sign:
3/2 + sqrt(5) - 3/2 + sqrt(5)
Next, combine the like terms:
(3/2 - 3/2) + sqrt(5) + sqrt(5)
3/2 - 3/2 equals 0, so we are left with:
0 + 2sqrt(5)
Therefore, the final answer is:
2sqrt(5)
