49 x^{2} - 3 = 13

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

Solution steps

49 x^{2} - 3 = 13

Move

3

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}

2 x \cdot (x - 3) - x \cdot (x - 3) = 0

x^{2} - 2 x + 1 - x = - 2 x^{2} + x

5 (x - 2)^{2} = - 20

- x^{2} + 7 x + 3 = 0

x (2 x + 3) - 5 = 6 x
