5sqrt(x-3)+2sqrt(x+1)=sqrt(x+13)

5 x - 3 + 2 x + 1 = x + 13

x = 3

Solution steps

5 x - 3 + 2 x + 1 = x + 13

Remove square roots

400 x^{2} - 800 x - 1200 = 784 x^{2} - 4704 x + 7056

Solve

400 x^{2} - 800 x - 1200 = 784 x^{2} - 4704 x + 7056 : x = 3, x = \frac{43}{6}

x = 3, x = \frac{43}{6}

Verify Solutions:

x = 3

True

, x = \frac{43}{6}

False

The solution is

x = 3

t, 89 f = \frac{( 1 - 2 t )}{( 1 + 2 t )}

x^{2} + 3 3 x - 30 = 0

x x + x - x = 2 x

b = - x - 4 x

(x + 28)^{\frac{1}{3}} - (x - 28)^{\frac{1}{3}} = 2
