1.	If two zeroes of the polynomial x3 – 5x2 + 2x + d are respectively – 1 and 2, then evaluate d.
Answer» Liner equation and two variyebal By putting the value of x as -1 and 2 one by one the given polynomial 1) when x=-1(-1)^3-5(-1)2+2(-1)+d=0 # -1-5-2+d=0 # d=8Similarly on putting the value of x as 2 we will get d=8.Therefore the required value of d=8.Hope it will be helpful Join betternation.xyz This is a site where u can have a lot of friends and fun ? ? ?
