- 100 = - 4.9 t^{2}

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

Solution steps

- 100 = - 4.9 t^{2}

Switch sides

- 4.9 t^{2} = - 100

Multiply both sides by

10

- 49 t^{2} = - 1000

Divide both sides by

- 49

t^{2} = \frac{1000}{49}

For

x^{2} = f (a)

the solutions are

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

t = \frac{1000}{49}, t = - \frac{1000}{49}

\frac{1000}{49} = \frac{10 10}{7}

- \frac{1000}{49} = - \frac{10 10}{7}

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

x^{2} - 13 = 60

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

x (x + 8) = 20

3 x^{2} - 18 x + 11

5 n^{2} + 7 n - 3 = 4 n
