Simplify 5(a - b) + 6(a + b) - 7(a - 2b)
4a - 13b
4a + 15b
19ab

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares
