factor z^2-11z-12

factor

z^{2} - 11 z - 12

(z + 1) (z - 12)

Solution steps

z^{2} - 11 z - 12

Break the expression into groups

= (z^{2} + z) + (- 12 z - 12)

Factor out

z

from

z^{2} + z : z (z + 1)

Factor out

- 12

from

- 12 z - 12 : - 12 (z + 1)

= z (z + 1) - 12 (z + 1)

Factor out common term

z + 1

= (z + 1) (z - 12)

\frac{1}{\frac{3}{3}}

\frac{x ( x + 2 )}{4 x ^{2} - 9} < \frac{1}{5}

64 x^{3} - y^{6}
