Best ResponseYou've already chosen the best response.0Assuming you meant $$ x^28x9=0 $$ What two numbers, a and b multiply to give you 9 and subtract to give you 8 $$ ab=9\\ a+b=8 $$ Then $$ x^28x9=(x+a)(x+b)=0 $$ Then set each term to 0, solve for x: $$ x+a=0\\ x+b=0 $$ x=a and x=b are your solutions. That's it!
