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

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

x = 4

Solution steps

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 2 = 0 or x - 2 = 0

Solve

x + 2 = 0 :

No Solution for

x \in R

Solve

x - 2 = 0 : x = 4

x = 4

Verify Solutions:

x = 4

True

The solution is

x = 4

x, y = 14 x

6 x + 2 = 7 x

100 = x^{0.25}

(4 x - 4)^{\frac{3}{2}} - 2 = 214

2 g + 0.575 = 4.6056
