factor z^2-9z+14

factor

z^{2} - 9 z + 14

(z - 2) (z - 7)

Solution steps

z^{2} - 9 z + 14

Break the expression into groups

= (z^{2} - 2 z) + (- 7 z + 14)

Factor out

z

from

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

Factor out

- 7

from

- 7 z + 14 : - 7 (z - 2)

= z (z - 2) - 7 (z - 2)

Factor out common term

z - 2

= (z - 2) (z - 7)

9 x^{2} - 3 x - 12 = 0

5 (j - 4) + j = - 8

x^{2} - 14 x + 48 \leq 0

(- 5 x^{3} y)^{3}

\frac{11 \cdot 20 i}{11 + 20 i}
