factor 3z^2+23z+30

factor

3 z^{2} + 23 z + 30

(3 z + 5) (z + 6)

Solution steps

3 z^{2} + 23 z + 30

Break the expression into groups

= (3 z^{2} + 5 z) + (18 z + 30)

Factor out

z

from

3 z^{2} + 5 z : z (3 z + 5)

Factor out

6

from

18 z + 30 : 6 (3 z + 5)

= z (3 z + 5) + 6 (3 z + 5)

Factor out common term

3 z + 5

= (3 z + 5) (z + 6)

- x^{3} + a^{3}

1 + 3 u < 10

\frac{1}{x - 1} < \frac{2}{x + 2}

\frac{3}{10} x - 2 x + \frac{6}{5} = \frac{3}{5}

\frac{8}{x - 2} \geq 2
