Answer»

-36; is the correct answer of the given question

-36 is a right answer

-36 is the correct answer

-,36,is the right answer

-36is correctanswer

this is correct option

x²-5x+k=0...(i)one of the zero is -4so let x=-4putting in (i) we get(-4)²-5(-4)+k=016+20+k=036+k=0thereforek=-36so option (b) is the correct answer
