x^{2} + x - 56

(x - 7) (x + 8)

= (x^{2} - 7 x) + (8 x - 56)

Factor out

x

from

x^{2} - 7 x : x (x - 7)

Factor out

8

from

8 x - 56 : 8 (x - 7)

= x (x - 7) + 8 (x - 7)

Factor out common term

x - 7

= (x - 7) (x + 8)

\frac{x}{2} = \frac{3}{9}

3 π x = 0

\frac{3 x}{2} = \frac{3}{8}

3 x^{2} - 2 x - 6 = 0
