Factoring the Expression (m-4)(m^2+4m-5)
This expression represents a product of two factors:
- (m - 4): This is a simple binomial.
- (m^2 + 4m - 5): This is a quadratic trinomial.
To fully simplify the expression, we need to factor the quadratic trinomial.
Factoring the Trinomial
We can factor the trinomial by finding two numbers that:
- Multiply to give -5 (the constant term).
- Add up to 4 (the coefficient of the middle term).
These two numbers are 5 and -1. So, we can rewrite the trinomial as:
(m^2 + 4m - 5) = (m + 5)(m - 1)
Final Result
Now, we can substitute the factored trinomial back into the original expression:
(m - 4)(m^2 + 4m - 5) = (m - 4)(m + 5)(m - 1)
Therefore, the fully factored form of the expression (m - 4)(m^2 + 4m - 5) is (m - 4)(m + 5)(m - 1).
