xx + 4 - 2 x + 12 = 0

x \approx - 1.56831 \dots, x \approx 1.85599 \dots

Solution steps

xx + 4 - 2 x + 12 = 0

Expand

xx + 4 - 2 x + 12 : x^{2} + 4 - 2 x + 12

x^{2} + 4 - 2 x + 12 = 0

Remove square roots

4 x + 48 = x^{4} + 8 x^{2} + 16

Solve

4 x + 48 = x^{4} + 8 x^{2} + 16 : x \approx - 1.56831 \dots, x \approx 1.85599 \dots

x \approx - 1.56831 \dots, x \approx 1.85599 \dots

Verify Solutions:

x \approx - 1.56831 \dots

True

, x \approx 1.85599 \dots

True

The solutions are

x \approx - 1.56831 \dots, x \approx 1.85599 \dots

x, a x - y + c = b

x - 2 = 5 x + 1

8 = 64 n

- (0) + 2 y = 1

(x^{2} + 21)^{\frac{1}{2}} = 5
