Answer:
2x²+3x+m=0
Put X=1/2
1/2+3/2+m=0
m=-2
Then,
2x²+3x-2=0
2x²+4x-x-2=0
2x(x+2)-1(x+2)=0
(2x-1)(X+2)=0
x=1/2 and X= -2

Answer:
Step-by-step explanation:
Zero of p(x) is 1/2
So,
Put value of x 1/2
2x²+3x+m=0
2(1/2)²+3(1/2)+m=0
2/4+3/2+m=0
1/2+3/2+m=0
4/2+m=0
2+m=0
m=-2
2x²+3x-2=0
By splitting the middle term
2x²+4x-x-2=0
2x(x+2)-1(x+2)=0
(2x-1)(x+2)=0
2x-1=0
x=1/2
x+2=0
x=-2
Hope it helps you
