Question

8. What is the solution to the equation √(2x+8 )-6=4

Answer 1

x=15

Answer 2

how u gott x=15 @dejavo

Answer 3

√(2x+8 )-6=4
√(2x+8 )=4+6
√(2x+8 )=10
taking square on both sides
then
2x + 8=10 x 10
2x+8=100
2x=100-8
2x=92
x=92\2
x=46
verification
put the value of x in given equation
√(2(46)+8 )-6=4
\[\sqrt{92+8}-6=4\]
\[\sqrt{100}-6=4\]
100 is square of 10
10-6=4
4=4
Hence proved
x=46
This is the correct answer

Answer 4

x=1
