sqrt(2-7x)+2x=0

Solution

2 - 7 x + 2 x = 0

Solution

x = - 2

Solution steps

2 - 7 x + 2 x = 0

Remove square roots

2 - 7 x = 4 x^{2}

Solve

2 - 7 x = 4 x^{2} : x = \frac{1}{4}, x = - 2

x = \frac{1}{4}, x = - 2

Verify Solutions:

x = \frac{1}{4}

False

, x = - 2

True

The solution is

x = - 2

Popular Examples

x=2xsqrt(25-x^2)

x = 2 x 25 - x^{2}

sqrt(128)=sqrt(x)+sqrt(2)

128 = x + 2

x^{2} = - x

sqrt(3+\sqrt{3+\sqrt{3+x)}}=x

3 + 3 + 3 + x = x

(3 x + 1)^{\frac{3}{4}} = 8
