80 + y^{2} = 81

y = 1, y = - 1

Solution steps

80 + y^{2} = 81

Move

80

to the right side

y^{2} = 1

For

x^{2} = f (a)

the solutions are

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

y = 1, y = - 1

1 = 1

- 1 = - 1

y = 1, y = - 1

- x^{2} - 3 x - 4 = 0

20 - b^{2} = - 5

3 q (q - 3) = 12

x^{2} + 3 x + \frac{13}{4}

2 x^{2} = 25
