20 x^{2} = 245

x = \frac{7}{2}, x = - \frac{7}{2}

Decimal Notation

x = 3.5, x = - 3.5

Solution steps

20 x^{2} = 245

Divide both sides by

20

x^{2} = \frac{49}{4}

For

x^{2} = f (a)

the solutions are

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

x = \frac{49}{4}, x = - \frac{49}{4}

\frac{49}{4} = \frac{7}{2}

- \frac{49}{4} = - \frac{7}{2}

x = \frac{7}{2}, x = - \frac{7}{2}

- 10 x + 2 = - 3 + 8 x

\frac{4}{3 a - 6} + \frac{7}{5 a - 10}

- 10 x = - 25 - x^{2}

2 p^{2} + p

\frac{( 1.15 \cdot 1 0 ^{- 3} )}{( 8.92 \cdot 1 0 ^{3} )}
