anonymous · Answer

it doesn't matter if 2a or 3a goes first, the negative is applied to the entire equation. (2a-3)(3a+5) = 6a^2+a-15 so the - needs to be put out front because you multiply each variable by it.

its like saying -(6a^2+a-15)

the answer on my sheet gives only one answer of (5+3a)(3-2a)...which means that applied it to (2a-3)
