Best ResponseYou've already chosen the best response.0\[f(a) = 3a^2x+2\]\[[ f(a) ]^2 = [ 3a^2x+2 ] ^2 = [3a^2x+2][3a^2x+2]\] can you go from here?

Best ResponseYou've already chosen the best response.0\[[3a^2−a+2][3a^2−a+2] = (3a^2)(3a^2)+(3a^2)(a)+(3a^2)(2)+(a)(3a^2)+(a)(a)+(a)(2)+(2)(3a^2)+(2)(a)+(2)(2)\]

Best ResponseYou've already chosen the best response.0but basically its: \[[3a^2−a+2][3a^2−a+2] = \] \[(3a^2)(3a^2)+(3a^2)(a)+(3a^2)(2)\]\[+(a)(3a^2)+(a)(a)+(a)(2) \]\[+(2)(3a^2)+(2)(a)+(2)(2)=\] \[9a^4  3a^3 3a^3 + 6a^2 a^2+6a^22a2a+4\] is that better?
