0 = 9 x^{2} - 49

x = \frac{7}{3}, x = - \frac{7}{3}

Decimal Notation

x = 2.33333 \dots, x = - 2.33333 \dots

Solution steps

0 = 9 x^{2} - 49

Switch sides

9 x^{2} - 49 = 0

Move

49

to the right side

9 x^{2} = 49

Divide both sides by

9

x^{2} = \frac{49}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{49}{9}, x = - \frac{49}{9}

\frac{49}{9} = \frac{7}{3}

- \frac{49}{9} = - \frac{7}{3}

x = \frac{7}{3}, x = - \frac{7}{3}

4 x + 16 = 2 x^{2} + 10

x^{2} + \frac{8}{3} x + \frac{16}{9} = 0

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

x^{2} - 10 x + 21

(- \frac{8}{3})^{2} + y^{2} = 1^{2}
