Trying to ask my method of doing the question is correct or not? Try check is there any mistake please? I am beginner. The Question Find the real solutions to each of the following questions. (a) X³+X²-10X+8=0 My attempt at a solution X³+X²-10X+8=0 f(1)=1³+1²-10(1)+8 f(1)=0 X=1 X-1=0 (one of the factor) X³+X²-10X+8=(X-1)(X²+kX-8) Compare the coefficient X² X²=kX²-X² 1=k-1 2=k X²+X-8=(X-2)(X+4) The factors are (X-1)(X-2)(X+4) **(From here start my working wonder correct or wrong)*** 1st Method of answering (X-1)(X-2)(X+4)=0 X-2=0, X-1=0, X+4=0 X=2, X=1, X=-4 # 2nd Method of answering f(X)=(X-1)(X-2)(X+4) f(X)=0 (X-1)(X-2)(X+4)=0 X-2=0, X-1=0, X+4=0 X=2, X=1, X=-4 # The 1st Method of answering or 2nd is correct?
