sqrt(25+5x)+sqrt(3x+31)=4

25 + 5 x + 3 x + 31 = 4

x = - 5

Solution steps

25 + 5 x + 3 x + 31 = 4

Remove square roots

4 x^{2} - 88 x + 484 = 192 x + 1984

Solve

4 x^{2} - 88 x + 484 = 192 x + 1984 : x = 75, x = - 5

x = 75, x = - 5

Verify Solutions:

x = 75

False

, x = - 5

True

The solution is

x = - 5

x + c^{2} + a = 2 b

\frac{x - 1}{4} = x - 4

\frac{4}{3 x ^{\frac{4}{3}}} = 0

\frac{3 x - 2 a}{2 x - a} = 0

5 x + 7 = 20
