x-2sqrt(x)-6=0

x - 2 x - 6 = 0

x = 2 (4 + 7)

Decimal Notation

x = 13.29150 \dots

Solution steps

x - 2 x - 6 = 0

Remove square roots

4 x = x^{2} - 12 x + 36

Solve

4 x = x^{2} - 12 x + 36 : x = 2 (4 + 7), x = 2 (4 - 7)

x = 2 (4 + 7), x = 2 (4 - 7)

Verify Solutions:

x = 2 (4 + 7)

True

, x = 2 (4 - 7)

False

The solution is

x = 2 (4 + 7)

(x - 6)^{\frac{1}{2}} = 4

120 = \frac{t}{0.005}

k, f = k^{\frac{1}{3}} \cdot l^{\frac{1}{2}}

289 + x = \frac{( 1 )}{( 5 )}

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