Let f(x) = 2x2 + 5x - 3, g(x) = x2 -4x + 2, and h(x) = -x2 + 4x - 2. Select all of the expressions that are equivalent to 3x2 + x -1.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
