x^{2} + x^{2} = 20

x = 102, x = - 102

Decimal Notation

x = 14.14213 \dots, x = - 14.14213 \dots

Solution steps

x^{2} + x^{2} = 20

Square both sides:

2 x^{2} = 400

2 x^{2} = 400

Solve

2 x^{2} = 400 : x = 102, x = - 102

x = 102, x = - 102

Verify Solutions:

x = 102

True

, x = - 102

True

The solutions are

x = 102, x = - 102

x^{2} + x^{2} = 16

2 x + 3 = - x

a^{\frac{1}{6}} = 2

0 = 8 x + 7

7 - 3 z + 2 = 4
