x^{2} - 4 = x - 4

No Solution for x \in R

Solution steps

x^{2} - 4 = x - 4

Square both sides:

x^{2} - 4 = x^{2} - 8 x + 16

x^{2} - 4 = x^{2} - 8 x + 16

Solve

x^{2} - 4 = x^{2} - 8 x + 16 : x = \frac{5}{2}

x = \frac{5}{2}

Verify Solutions:

x = \frac{5}{2}

False

The solution is

No Solution for x \in R

x - 55 = 6 x^{\frac{1}{2}}

x + 0 - 7 = 10

264 - x^{2} - 14 = - 6

x - 16 x - 512 = 0
