49 x^{2} - 16 = 0

x = \frac{4}{7}, x = - \frac{4}{7}

Solution steps

49 x^{2} - 16 = 0

Move

16

to the right side

49 x^{2} = 16

Divide both sides by

49

x^{2} = \frac{16}{49}

For

x^{2} = f (a)

the solutions are

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

x = \frac{16}{49}, x = - \frac{16}{49}

\frac{16}{49} = \frac{4}{7}

- \frac{16}{49} = - \frac{4}{7}

x = \frac{4}{7}, x = - \frac{4}{7}

9 x^{2} - 3 x - 1 = 0

x - 1 + 2 x - 1 = - 5

2 w^{2} + 3 w - 77

2 x = 9 - x^{2}

882 = - 13.957 x^{2} + 310.63 x + 31.971
