x^{2} + 2 x - 8

(x - 2) (x + 4)

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

Factor out

x

from

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

Factor out

4

from

4 x - 8 : 4 (x - 2)

= x (x - 2) + 4 (x - 2)

Factor out common term

x - 2

= (x - 2) (x + 4)

lo g_{2} (3) + lo g_{2} (5)

x^{4} - 36 x^{2}

\frac{3}{10} = \frac{x}{7}

6 x^{2} y + 7 x y^{2} + y^{3}

\frac{4 x - 3}{2} \geq - 3.5
