Factorise x^2+x-2.guys solve it fast,and then tell me the zeros of this polynomial |

Answer» if x-1=0 x=+1 x^2+x-2 f(x)= x^2+x-2 f(1)= 1^2+1-2 f(1)=2-2 f(1)=0 so one FACTOR is (x-1)=0 X=1 Another one is if x+2=0 x=-2 f(x)=x^2+x-2 f(-2)=-2^2+(-2)-2 f(-2)=0 Now factor are x=1 x=-2 Hope it HELPS u^_^ |
