Complete the statements to explain how to factor x2 + x – 12 using algebra tiles.
represent the trinomial using 1 positive x2-tile,
_1 positive x tile_, and _12 negative unit tiles_ .
form a rectangle with the tiles, adding zero pairs as needed. how many zero pairs are needed? _3_
drag tiles onto the board to represent each factor. what is the factorization? x2+x – 12 = _(x - 3)(x + 4)_

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
