factor 2z^2+3z-20

factor

2 z^{2} + 3 z - 20

(2 z - 5) (z + 4)

Solution steps

2 z^{2} + 3 z - 20

Break the expression into groups

= (2 z^{2} - 5 z) + (8 z - 20)

Factor out

z

from

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

Factor out

4

from

8 z - 20 : 4 (2 z - 5)

= z (2 z - 5) + 4 (2 z - 5)

Factor out common term

2 z - 5

= (2 z - 5) (z + 4)

- 4 \leq x + 5 \leq 5

ln (\frac{1}{e ^{5}}) = y

(x + 2) (x - 3) = 0

10 (1 + 3 b) = - 20

m^{2} - 3 m = 0
