Answer:
u= 3
Explanation:
Isolate a square root on the left hand side
Original equation
√5u-10-√2u-1 = 0
Isolate
√5u-10 = √2u-1+0
Eliminate the radical on the left hand side
Raise both sides to the second power(√5u-10)2 = (√2u-1)2 After squaring
5u-10 = 2u-1
Solve the linear equation
Rearranged equation
3u -9 = 0
Add 9 to both sides
3u = 9
Divide both sides by 3
A possible solution is :
u = 3
