Best ResponseYou've already chosen the best response.1First, right it as two binomials: (x1/2)(x1/2) Then, use FOIL: Firsts: x^2 Outers: 1/2x Inners: 1/2x Lasts: 1/4 So you get x^2x+1/4

Best ResponseYou've already chosen the best response.0Ok so this is where I'm at: (x  1/2) (x  1/2) x^2 1/2x12x2.25

Best ResponseYou've already chosen the best response.0well 1.5 * 1.5= 2.25 Oh so its: x^2 1/2x1/2x+ 2.25 Yah?

Best ResponseYou've already chosen the best response.1It's 1/2, not 1.5, right? 1/2*1/2 = 1/4
