Hello student, Please find the soluitonif x2-1 is a factor of ax4+bx3+cx2+dx+e=> x = +1 and -1 are the roots of ax4+bx3+cx2+dx+eNow if f(x) = ax4+bx3+cx2+dx+ethan f(+1)=f(-1)=0so a+b+c+d+e=0 ….….….(1)and a-b+c-d+e = 0 ….…....(2)Hence from (1) and (2),a+c+e=b+d=0I hope the solution is clearThank you
