Please help me factor this trinomial

[From: ] [author: ] [Date: 12-05-21] [Hit: ]
Hope this helps!-You need to find two numbers whose product is -54 and whose sum is -3.......
b^3-3b^2-54b
please factor.
thanks so much!

Because every term has a b you can factor out the gcf of b
b(b²-3b-54)
Now factor the quadratic
b(b-9)(b+6) <---- Answer

-
b^3 - 3b^2 - 54b

You can factor b out of this trinomial.

b(b^2 - 3b - 54)

Then, factor what is in the parentheses.

b(b+6)(b-9)

Hope this helps!

You need to find two numbers whose product is -54 and whose sum is -3. Those two numbers are -9 and 6

b(b - 9)(b + 6)

-
b^3-3b^2-54b = b(b-9)(b+6)
