solve for

y, x^{2} + y^{2} = 81

y = 81 - x^{2}, y = - 81 - x^{2}

Solution steps

x^{2} + y^{2} = 81

Move

x^{2}

to the right side

y^{2} = 81 - x^{2}

For

x^{2} = f (a)

the solutions are

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

y = 81 - x^{2}, y = - 81 - x^{2}

8^{2} + b^{2} = 9^{2}

2 y^{2} + y - 2 = 0

- 2 (x + 3)^{2} + 8 = 0

x^{2} - 9 x + 8 = 0

- 5 x^{2} - 7 x + 5 = 0
