20 - 4.9 (x)^{2} = 10

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

Decimal Notation

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

Solution steps

20 - 4.9 x^{2} = 10

Move

20

to the right side

- 4.9 x^{2} = - 10

Multiply both sides by

10

- 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^{3} + 8 x^{2} - 4 x - 32

\frac{n}{5} + 45 = 54

- 90 + 27 x^{2}

n^{2} + 3 n = 0
