400 = x^{2}

x = 20, x = - 20

Solution steps

400 = x^{2}

Switch sides

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

s^{2} + 25 = 0

3 x^{2} - 41 x + 110 = 0

3 k (k - 4) + k + 4 (k + 1) = 0

(2 x + 3) (x - 5) = 0

m^{2} - 6 m + 5 = 0
