factor the trinomial below
x^2-4x-21
To factor the trinomial x^2 - 4x - 21, we need to find two numbers that multiply to -21 and add up to -4. These numbers are -7 and 3.
Therefore, the factored form of the trinomial is:
(x - 7)(x + 3)
x^2-4x-21
Therefore, the factored form of the trinomial is:
(x - 7)(x + 3)
