4 (7 - 7 x^{2}) = 7

x = \frac{3}{2}, x = - \frac{3}{2}

Solution steps

4 (7 - 7 x^{2}) = 7

Divide both sides by

4

7 - 7 x^{2} = \frac{7}{4}

Move

7

to the right side

- 7 x^{2} = - \frac{21}{4}

Divide both sides by

- 7

x^{2} = \frac{3}{4}

For

x^{2} = f (a)

the solutions are

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

x = \frac{3}{4}, x = - \frac{3}{4}

\frac{3}{4} = \frac{3}{2}

- \frac{3}{4} = - \frac{3}{2}

x = \frac{3}{2}, x = - \frac{3}{2}

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

x (x - 7) = 2 x

x (x - c) = a

9.81 t^{2} - 24 t - 140 = 0

g^{2} + 34 = - 135
