Question

tell this tick the right snswer

Answer 1

(1) x^2+kx+6=(x+2)(x+3)
so,x^2+kx+6=x^2+2x+3x+6
thus,x^2+kx+6=x^2+5x+6
on comparing the coefficient of same term on both the sides , we get the value of k=5, (C)

(2) Here, polynomial is root2x-1, (B)

(3)Root 2 has a degree 0, (B)

(4)The degree of p (x) is 5, (B)
