Best ResponseYou've already chosen the best response.0The graph of this function passes through the xaxis at the points where the polynomial = 0 ie whwn x = 1, 3 and 4. OK first deal with (x+1)(x+4): first multiply (x+4 by x giving x^2 + 4x then multiply (x + 4) by +1 giving x + 4 Adding these together gives x^2 + 4x + x +4 = x^2 + 5x + 4 Finally we multiply x^2 + 5x + 4 by the other term (x + 3): as before first multiply by x then by 3 then add the results together does this explain it ok? If not get back to me

Best ResponseYou've already chosen the best response.0does it matter what we deal with first? why (x+1)(x+4) and not (X+1)(x+3)
