sqrt(x+1)+sqrt(2x+3)=5

x + 1 + 2 x + 3 = 5

x = 3

Solution steps

x + 1 + 2 x + 3 = 5

Remove square roots

x^{2} + 54 x + 729 = 200 x + 300

Solve

x^{2} + 54 x + 729 = 200 x + 300 : x = 143, x = 3

x = 143, x = 3

Verify Solutions:

x = 143

False

, x = 3

True

The solution is

x = 3

2 x - 3 = - 1

x, (a) f = - 6 - 3 x

4 x + 9 = 5

1 - 2 x = 4 x + 33

x - 16 - x + 8 = - 4
