49 x^{2} - 100 = 0

x = \frac{10}{7}, x = - \frac{10}{7}

Decimal Notation

x = 1.42857 \dots, x = - 1.42857 \dots

Solution steps

49 x^{2} - 100 = 0

Move

100

to the right side

49 x^{2} = 100

Divide both sides by

49

x^{2} = \frac{100}{49}

For

x^{2} = f (a)

the solutions are

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

x = \frac{100}{49}, x = - \frac{100}{49}

\frac{100}{49} = \frac{10}{7}

- \frac{100}{49} = - \frac{10}{7}

x = \frac{10}{7}, x = - \frac{10}{7}

x^{2} - 8 x + c = 0

(x + 1) (x - 5) = 16

a^{2} - 8 a + 16 = 0

x^{2} - 34 = 16 x

9 x^{2} - 24 = 1
