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

x = 15, x = - 15

Decimal Notation

x = 3.87298 \dots, x = - 3.87298 \dots

Solution steps

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

Move

7^{2}

to the right side

x^{2} = 15

For

x^{2} = f (a)

the solutions are

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

x = 15, x = - 15

x^{2} - 16 = 59

2 x^{2} + 3 - 2 = 0

- 25 x^{2} + 15 x - 2 = 0

(2 x + 5)^{2} = 18
