factor z^2+z-30

factor

z^{2} + z - 30

(z - 5) (z + 6)

Solution steps

z^{2} + z - 30

Break the expression into groups

= (z^{2} - 5 z) + (6 z - 30)

Factor out

z

from

z^{2} - 5 z : z (z - 5)

Factor out

6

from

6 z - 30 : 6 (z - 5)

= z (z - 5) + 6 (z - 5)

Factor out common term

z - 5

= (z - 5) (z + 6)

- \frac{35}{2} (\frac{1}{10 0 ^{2}}) + \frac{35}{2}

2 a = - a

5 x + \frac{1}{2} - 3 < 9

x^{2} - 4 + 3

- 5 (20 x) = 100
