x^2-1=sqrt(-4x)

x^{2} - 1 = - 4 x

x \approx - 1.94696 \dots

Solution steps

x^{2} - 1 = - 4 x

Square both sides:

x^{4} - 2 x^{2} + 1 = - 4 x

x^{4} - 2 x^{2} + 1 = - 4 x

Solve

x^{4} - 2 x^{2} + 1 = - 4 x : x \approx - 0.22527 \dots, x \approx - 1.94696 \dots

x \approx - 0.22527 \dots, x \approx - 1.94696 \dots

Verify Solutions:

x \approx - 0.22527 \dots

False

, x \approx - 1.94696 \dots

True

The solution is

x \approx - 1.94696 \dots

x = \frac{1}{2}

0 = 18 5 x + 10

x + 2 x + 1 = 7

x - 4 = 40 - 6 x

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