sqrt(4x^2)=8

Solution

4 x^{2} = 8

Solution

x = 4, x = - 4

Solution steps

4 x^{2} = 8

Square both sides:

4 x^{2} = 64

4 x^{2} = 64

Solve

4 x^{2} = 64 : x = 4, x = - 4

x = 4, x = - 4

Verify Solutions:

x = 4

True

, x = - 4

True

The solutions are

x = 4, x = - 4

Popular Examples

x+9=sqrt(x^2+4x+4)

x + 9 = x^{2} + 4 x + 4

x=1-1/(sqrt(x+1))

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

y^{\frac{3}{2}} = 8

2 x + 3 - 3 = 0

4=4-sqrt((2x^0)/3)

4 = 4 - \frac{2 x ^{0}}{3}
