If you are using algebra tiles to factor a trinomial of the
form ax? + bx + c, when would you need to bring in zero
pairs? Why?
If the value of c is negative. you would need zero pairs to model the factorization
of the polynomial
Sample Response: If the value of c is negative, you
would need zero pairs to model the factorization of t1
polynomial. The x-tiles on the board determine what
the constants are in the factors. The product of these
constants is equal to the value of c, so you would need
positive tiles on one side of the x-squared tile and
negative x-tiles on the other side to have opposite sig
on the constants. Opposite signs on the constants will
result in a negative value for c when multiplying the
factors.

You would need both positive and negative x-til
