factor 3z^2-2z-5

factor

3 z^{2} - 2 z - 5

(z + 1) (3 z - 5)

Solution steps

3 z^{2} - 2 z - 5

Break the expression into groups

= (3 z^{2} + 3 z) + (- 5 z - 5)

\frac{1}{2} (14)

4 x^{2} - 3 = - 4 + 7 x

2 x^{3} - 2 x^{2} - 112 x

2 n^{2} + 2 n - 4 = 0

\frac{\frac{1}{6 + x + h} - \frac{1}{6 + x}}{h}
