hmm HallsofIvy, this is mine error? The factors are (X-1)(X-2)(X+4) NO, they aren't. That's your error Should it be The factors are (X-1),(X-2),(X+4)? put commas between each factor?

Yeah i found that i accidentally wrote X²+x-8 without the 2 inside. HallsofIvy, maybe you right over here that X²+2X-8=(X-2)(X+4), or i should write X²+2X-8=0 (X-2)(X+4)=0? I study Mathematics T that is A-level or Pre-U i think. Higher School Certificate (HSC). The HSC was the precursor to...
