x^{2} + 1 = 3

x = 22, x = - 22

Decimal

x = 2.82842 \dots, x = - 2.82842 \dots

Solution steps

x^{2} + 1 = 3

Square both sides:

x^{2} + 1 = 9

x^{2} + 1 = 9

Solve

x^{2} + 1 = 9 : x = 22, x = - 22

x = 22, x = - 22

Verify Solutions:

x = 22

True

, x = - 22

True

The solutions are

x = 22, x = - 22

\frac{5}{9} x^{\frac{5}{3}} + 92 = - 43

5 x^{\frac{4}{5}} = 0

x = 2 x

x + 3 - 5 = 0

x + 6 + x + 11 = 5 - 10 x
