7 x^{2} - 9 = 2

x = \frac{11}{7}, x = - \frac{11}{7}

Decimal Notation

x = 1.25356 \dots, x = - 1.25356 \dots

Solution steps

7 x^{2} - 9 = 2

Move

9

to the right side

7 x^{2} = 11

Divide both sides by

7

x^{2} = \frac{11}{7}

For

x^{2} = f (a)

the solutions are

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

x = \frac{11}{7}, x = - \frac{11}{7}

14 + 12 v = - 16 + 9 v

(5 x)^{2} + (5 x + 5)^{2} = (5 x + 10)^{2}

5^{x + 2} - 5^{x - 1}

0.0 1^{2}

5 x^{2} + 20 x
