1. ### SOLVE FOR U WHERE U IS A REAL NUMBER?

u ^2 = -2u + 15 u ^2 + 2u - 15 = 0 u ^2 + 5u - 3u - 15 = 0 u ( u + 5) - 3( u + 5) = 0 ( u - 3)( u + 5) = 0 u - 3 = 0 or u + 5 = 0 u = 3 or u = -5 If u = 3 we have: 3 = sqrt(-2*3 + 15) 3 = sqrt(-6 + 15) 3 = sqrt(9) TRUE If u = -5...

3. ### using u substitution integrate?

∫ [x /(10 - √x)] dx = let (10 - √x) = u → √x = 10 - u → square both sides: x = (10 - u )² → dx = 2...3(10)u² - u³] / u } du = distribute and break it into: - 2 ∫ (1000/ u ) du + 2 ∫ [(300u)/ u ] du - 2 ∫ [(30u²)/ u ] du + 2 ∫ (u³/ u ) du = pull...
