8^{2} + 1 5^{2} = r^{2}

r = 17, r = - 17

Solution steps

8^{2} + 1 5^{2} = r^{2}

Switch sides

r^{2} = 8^{2} + 1 5^{2}

Simplify

8^{2} + 1 5^{2} : 289

For

x^{2} = f (a)

the solutions are

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

r = 289, r = - 289

289 = 17

- 289 = - 17

r = 17, r = - 17

20 x^{2} + 38 x + 5 = 0

3 x^{2} + 42 = 0

3 t^{2} - 4 = 0

3 (- 6 + x)^{2} + 2 (- 6) = 0

x, x^{2} + 2 x - 1 = 0
