Algebra I
Today we discussedWe reviewed factoring trinomials both with a leading coefficient of 1 and not 1 and then moved on to factoring the difference of squares.
Recall:
a2- b2
= (a + b)(a - b)
YOU CANNOT FACTOR a2 + b2 using any of the methods we've discussed so far....

Today we discussedWe reviewed adding and subtracting rational number (both positive and negative fractions) for both fractions with like denominators and unlike denominators. There are several cases, and we discussed regrouping and "borrowing/stealing" for some mixed number subtraction problems.
