Question

Solve this please with steps b^4-3b^3-10b^2

Answer 1

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))`
