root(x+5)-root(x-5)=2
root(x+5)=2-root(x-5)
x+5=4-4root(x-5)+x-5
4root(x-5)+6=0
root(x-5)=-3/2
x-5=9/4
x=9/4 +5
x=29/4
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
No. But sin2a equals 1 minus cos2a ... and ... cos2a equals 1 minus sin2a
square root of 8
5 times 2 square equals 20 minus 29 equals -9
It is probably a quiz question with nothing to do with mathematics.

If x equals the square root of ...., then you already have solved for x
square root -5 minus 14 or - square root -5 minus 14
square root of 8
5 times 2 square equals 20 minus 29 equals -9
If a equals 3 and b equals minus 5 then a minus b equals what
I think you mean "What does negative 10 minus 5 equal?" If not, please correct me. But, the correct answer would be -15 or negative 15.

Yes and x = 2+square root of 6 or x = 2-square root of 6
