sqrt(-4u+1)+sqrt(2u+4)=3

- 4 u + 1 + 2 u + 4 = 3

u = 0, u = - 2

Solution steps

- 4 u + 1 + 2 u + 4 = 3

Remove square roots

36 u^{2} + 144 u + 144 = 72 u + 144

Solve

36 u^{2} + 144 u + 144 = 72 u + 144 : u = 0, u = - 2

u = 0, u = - 2

Verify Solutions:

u = 0

True

, u = - 2

True

The solutions are

u = 0, u = - 2

(- 3 - 1)^{2} + (- 2 - y)^{2} = 5

0.376 = 1 - \frac{1}{x ^{0.62}}

x + 1 - x = 0

3 x + 1 = 2 x - 6

3 x + 1 = 2 x + 1
