Question

If one of the zeroes of the polynomial 2x^+3x+k is 1/2. find the value of k and other zer​

Answer 1

Z=C/A

1/2=k/2

k=1

Now,

Z+Y=-B/ A

1/2 + Y = -3/2

Y= -2

Answer 2

2x+3k+k

x=1/2

put x

1+3/2+k=0

2+3+2k=0

5+2k=0

k=-5/2

another zero will come by methods like completing the square or primefactorisation or many other
