Extranious solution is mostly when you take the square root of negative number
what you want to do is math stuff
translate
remember that
so
7.
add 2 to both sides
square both sides
cube root both sides
x+1=9
minus 1
x=8
8.
square both sides
using math
0=x²-5x-6
x=6 or -1
if we do x=-1, we get
√4=-2, which is kind of true, but we normally find the principal root (posiitive0
-1 is extraious
x=6
9.
add √(x-1) to both sides then square both sides
minus (x+5) from both sides
square both sides
using math
x=-1 or 15
if we had x=-1, we would be having √(-1-1) which is sqrt of negative which is not allowed
x=15
