x^{2} - 4 x + 5 + 2 x = 0

x \approx 0.80450 \dots, x \approx 2.85319 \dots

Solution steps

x^{2} - 4 x + 5 + 2 x = 0

Remove square roots

5 + 2 x = x^{4} - 8 x^{3} + 16 x^{2}

Solve

5 + 2 x = x^{4} - 8 x^{3} + 16 x^{2} : x \approx - 0.45413 \dots, x \approx 0.80450 \dots, x \approx 2.85319 \dots, x \approx 4.79643 \dots

x \approx - 0.45413 \dots, x \approx 0.80450 \dots, x \approx 2.85319 \dots, x \approx 4.79643 \dots

Verify Solutions:

x \approx - 0.45413 \dots

False

, x \approx 0.80450 \dots

True

, x \approx 2.85319 \dots

True

, x \approx 4.79643 \dots

False

The solutions are

x \approx 0.80450 \dots, x \approx 2.85319 \dots

x^{2}^{2} = 9

20 = 6 q + 1

2 + x = 3

\frac{( x + 2 )}{( x \cdot ( x - 2 ) )} = 0

x^{0.25} = \frac{1}{4}
