factor 21z^2+10z-16

factor

21 z^{2} + 10 z - 16

(3 z - 2) (7 z + 8)

Solution steps

21 z^{2} + 10 z - 16

Break the expression into groups

= (21 z^{2} - 14 z) + (24 z - 16)

Factor out

7 z

from

21 z^{2} - 14 z : 7 z (3 z - 2)

Factor out

8

from

24 z - 16 : 8 (3 z - 2)

= 7 z (3 z - 2) + 8 (3 z - 2)

Factor out common term

3 z - 2

= (3 z - 2) (7 z + 8)

\frac{x ^{2} + 4 x + 10}{x ^{2} - x - 12} > 0

\frac{- 2}{4}

4 (x - 4) + 19 = 3 (x + 3)

\frac{x ^{7} y ^{5} z ^{6}}{x ^{5} y ^{4} z ^{2}}

4 x^{2} + 20 x = 0
