x^{2} + 2 1^{2} = 2 9^{2}

x = 20, x = - 20

Solution steps

x^{2} + 2 1^{2} = 2 9^{2}

Move

2 1^{2}

to the right side

x^{2} = 400

For

x^{2} = f (a)

the solutions are

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

x = 400, x = - 400

400 = 20

- 400 = - 20

x = 20, x = - 20

- 2 x^{2} - 10 x - 12 = 0

9 x^{2} - 196 = 0

b^{2} - 5 b = 0

x^{2} + 14 x - 13 = 2

2 (x - 1)^{2} = 50
