Question

How do I find the value of a  when the function f(x)=(2x^3 -12x^2 +8x-48)/( x-6 ) when X < 6 and f(x)= x^2 + x + a when X >=6....

Comment: a should be -34 but it's giving me incorrect... what am I doing wrong here?

Any help would be much appreciated thanks guys

triciaal · Answer

do you know how to factor the function?

triciaal · Answer

what do you get when you divide the polynomial by (x-6)?

dumptybaby · Answer

of course. I get 2x^3 -12x^2 +8

triciaal · Answer

try again

dumptybaby · Answer

Is it incorrect? I can't think of any other way to do the factorization
