3 x^{2} - 13 = 0

x = \frac{13}{3}, x = - \frac{13}{3}

Decimal Notation

x = 2.08166 \dots, x = - 2.08166 \dots

Solution steps

3 x^{2} - 13 = 0

Move

13

to the right side

3 x^{2} = 13

Divide both sides by

3

x^{2} = \frac{13}{3}

For

x^{2} = f (a)

the solutions are

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

x = \frac{13}{3}, x = - \frac{13}{3}

4 5^{2} + 2 8^{2} = x^{2}

x^{2} + 1.8 \cdot 1 0^{- 5} x - 3.6 \cdot 1 0^{- 6} = 0

x^{2} - 16 = 9

x^{2} + 1.8 \cdot 1 0^{- 5} x - 1.8 \cdot 1 0^{- 6} = 0

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