x^{2} + x^{2} = 8^{2}

x = 42, x = - 42

Decimal Notation

x = 5.65685 \dots, x = - 5.65685 \dots

Solution steps

x^{2} + x^{2} = 8^{2}

Add similar elements:

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

2 x^{2} = 8^{2}

8^{2} = 64

2 x^{2} = 64

Divide both sides by

2

x^{2} = 32

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = 32, x = - 32

32 = 42

- 32 = - 42

x = 42, x = - 42

10 x^{2} - 5 = 85

x, x^{2} + y^{2} - 4 x - 8 y + 20 = 0

(x + 3)^{2} + 4 = 40

64 x^{2} = 100

7 x^{2} - 2 x + 8 = 0
