4 (45 + x^{2}) = 196

x = 2, x = - 2

Solution steps

4 (45 + x^{2}) = 196

Divide both sides by

4

45 + x^{2} = 49

Move

45

to the right side

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

x (x + 4) 2

2 x^{2} - 3 x = - x^{2} + 3 x

39.1179765 x - 4.9 x^{2} + 125 = 0

2 x^{2} - 1 x - 120 = 0
