49 x^{2} - 64 = 0

x = \frac{8}{7}, x = - \frac{8}{7}

Decimal Notation

x = 1.14285 \dots, x = - 1.14285 \dots

Solution steps

49 x^{2} - 64 = 0

Move

64

to the right side

49 x^{2} = 64

Divide both sides by

49

x^{2} = \frac{64}{49}

For

x^{2} = f (a)

the solutions are

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

x = \frac{64}{49}, x = - \frac{64}{49}

\frac{64}{49} = \frac{8}{7}

- \frac{64}{49} = - \frac{8}{7}

x = \frac{8}{7}, x = - \frac{8}{7}

x - 7 = 2 x + 1

12 a^{3} + 8 a^{2} + 15 a + 10

2 - x \geq 0

- 6 x^{2} - 4 x + 4 = 0

- 1 - 2
