Solve this please with steps b^4-3b^3-10b^2
gtnhenbr [62]

Answer:

Step-by-step explanation:

There's no "solving" to be done because its an expression, but im assuming the question wants you to factor.

b^4-3b^3-10b^2

First, factor out a b^2

b^2(b^2-3b-10)

Factor the trinomial. What two numbers multiply to equal -10 but add to equal -3? They are -5 and +2

b^2((b-5)(b+2))
