x^{2} - 9 = 40

x = 7, x = - 7

Solution steps

x^{2} - 9 = 40

Move

9

to the right side

x^{2} = 49

For

x^{2} = f (a)

the solutions are

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

x = 49, x = - 49

49 = 7

- 49 = - 7

x = 7, x = - 7

(2 x - 8)^{2} = 4

3 x = 6 x^{2}

3 (x - 2)^{2} - 12 = 0

(85 x - 0.5 x^{2}) - (45 x + 300) = 300

x^{2} + 16 = 4
