factor d^2+8d+15

factor

d^{2} + 8 d + 15

(d + 3) (d + 5)

Solution steps

d^{2} + 8 d + 15

Break the expression into groups

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

Factor out

d

from

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

Factor out

5

from

5 d + 15 : 5 (d + 3)

= d (d + 3) + 5 (d + 3)

Factor out common term

d + 3

= (d + 3) (d + 5)
