3 x (x - 3) = 3 - 9 x

x = 1, x = - 1

Solution steps

3 x (x - 3) = 3 - 9 x

Expand

3 x (x - 3) : 3 x^{2} - 9 x

3 x^{2} - 9 x = 3 - 9 x

Move

9 x

to the left side

3 x^{2} = 3

Divide both sides by

3

x^{2} = 1

For

x^{2} = f (a)

the solutions are

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

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

t, 0 = 0 + 17.2 \cdot t + \frac{1}{2} (- 9.8) t^{2}

\frac{x ^{2}}{2} + \frac{13 x}{20} = \frac{3}{2}

\frac{1}{2} \cdot 2.1 \cdot v^{2} = 6.5

12 y^{2} + 2 y - 2 = 0

q^{2} + 4 q + 4 = 0
