The function h(x) = 5x2 – x – 6 is the result of combining two functions using multiplication.Which functions could have been combined?

To check the multiplication, expand the functions in choice A: (5x − 6)(x + 1) = 5x² + 5x − 6x − 6 = 5x² − x − 6. This matches h(x), so the functions in choice A could have been combined.
