a^{2} - 9 = (a + 3) (a - 3)

True for all a

Solution steps

a^{2} - 9 = (a + 3) (a - 3)

Expand

(a + 3) (a - 3) : a^{2} - 9

a^{2} - 9 = a^{2} - 9

Move

9

to the right side

a^{2} = a^{2}

Move

a^{2}

to the left side

0 = 0

Both sides are equal

True for all a

4 (a x + 3) - 3 a x = 25 + 3 a

\frac{x}{- 8} = 2

3 x + 3 = 3 (x + 1)

6 (x + 3) = - 2 (x - 1)

f = 3 (1) - 2
