4.9 x^{2} = 78.4

x = 4, x = - 4

Solution steps

4.9 x^{2} = 78.4

Divide both sides by

4.9

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

x, x^{2} - y = y^{2} - x

21 x^{2} + 21 x - 254 = 0

t^{2} + 3 t - 6 = 0

x, x + y + z = f (x^{2} + y^{2} + z^{2})

a, a^{3} + b^{3} = (a + b)^{3}
