Question

find the solution set for this equation
-b^2-5b=0

Answer 1

I would first multiply both sides (and all terms) by -1
that way you get
b^2 +5b=0
now factor "b" out of each term.
can you do that ?

Answer 2

yes

Answer 3

you should get
b(b+5)=0

Answer 4

yes so

Answer 5

what do i do next

Answer 6

if you multiply two terms and you get zero, that means one or the other must be 0

Answer 7

so it is (-5,0)

Answer 8

you know
b*(b+5)=0
first case: b is zero. b=0
second case: b+5=0
to find b, add -5 to both sides to get
b+5-5= 0-5
or after simplifying
b= -5

so b can be 0 or -5

Answer 9

thank you it is correct
