Q:
The partial factorization of x2 β x β 12 is modeled with algebra tiles.Which unit tiles are needed to complete the factorization?
Accepted Solution
A:
Please write that as x^2 - x - 12 (the "^" symbol denotes exponentiation).
x^2 - x - 12 factors to (x + 3)(x - 4),Β Check this by multiplication:
x^2 + 3x - 4x - 12 = x^2 - x - 12 (OK).
