z^{2} + z^{2} = 9^{2}

z = \frac{9}{2}, z = - \frac{9}{2}

Decimal Notation

z = 6.36396 \dots, z = - 6.36396 \dots

Solution steps

z^{2} + z^{2} = 9^{2}

Add similar elements:

z^{2} + z^{2} = 2 z^{2}

2 z^{2} = 9^{2}

9^{2} = 81

2 z^{2} = 81

Divide both sides by

2

z^{2} = \frac{81}{2}

For

x^{2} = f (a)

the solutions are

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

z = \frac{81}{2}, z = - \frac{81}{2}

\frac{81}{2} = \frac{9}{2}

- \frac{81}{2} = - \frac{9}{2}

z = \frac{9}{2}, z = - \frac{9}{2}

6 x = 16 - x^{2}

(2 x - 7)^{2} = 81

0 = 5 x^{2} + 29 x - 6

6 x^{2} - 49 = 0

x^{2} = - 17 x
