Question 442812: AMP Parsing Error of []: Invalid expression '': syntax error at /home/ichudov/project_locations/algebra.com/templates/Algebra/Expression.pm line 203. . sqrt(2u+10)-2 sqrt(u)=0
Answer by kittycat1613(12) (Show Source): You can put this solution on YOUR website!
√(2u+10)-2√u=0
√(2u+10)=2√u *
(√(2u+10))^2=(2√u)^2
2u+10=4u
10=2u
u=5
Check
*√(2u+10)=2√u
√(2(5)+10=2√5
√(10+10)=2√5
√20=2√5
√4x5=2√5
2√5=2√5
Correct
Answer: u is 5
