factor z^2+8z+15

factor

z^{2} + 8 z + 15

(z + 3) (z + 5)

Solution steps

z^{2} + 8 z + 15

Break the expression into groups

= (z^{2} + 3 z) + (5 z + 15)

Factor out

z

from

z^{2} + 3 z : z (z + 3)

Factor out

5

from

5 z + 15 : 5 (z + 3)

= z (z + 3) + 5 (z + 3)

Factor out common term

z + 3

= (z + 3) (z + 5)

2 < 5 x - 8 \leq 12

15 = 7 + 8 b

4 x^{2} = 13 x - 3

7 x^{2} - 13 x - 2 = 0

12 a b^{3} + 20 b
