Best ResponseYou've already chosen the best response.1No, that was for division..you can horizontally multiply now.

Best ResponseYou've already chosen the best response.0quick question when we horizontally multipl would the numerator be x^2 + 2 3 or x+ 2 x 3?

Best ResponseYou've already chosen the best response.1None.. \(\sf (x+2)(x3)\) x * x = ? x * 3 = ? 2 * x = ? 2 * 3 = ?

Best ResponseYou've already chosen the best response.1Factor \(\sf x^2  3x  10\) from the numerator..tell me what you get.

Best ResponseYou've already chosen the best response.1Can you factor \(\sf x^2  3x  10\)?

Best ResponseYou've already chosen the best response.1Yes, so we have: \(\sf \dfrac{x+2}{(x5)(x+2)} \times \dfrac{x3}{x^2+x12}\) The x + 2's cancel out, giving us: \(\sf \dfrac{\cancel{x+2}}{(x5)(\cancel{x+2})} \times \dfrac{x3}{x^2+x12}\) \(\sf \dfrac{1}{(x5)} \times \dfrac{x3}{x^2+x12}\)

Best ResponseYou've already chosen the best response.1Now we multiply horizontally..but first factor \(\sf x^2 + x  12\).

Best ResponseYou've already chosen the best response.0but it would be \[\frac{ 1 }{ (x  5) } \times \frac{ 1 } { ( x + 4)}\]

Best ResponseYou've already chosen the best response.1Yes..which gives us: \(\sf \dfrac{1}{(x5)(x+4)}\)
