amishi14: question is right

Anonymous: the polynomial with 2 and -2 zeros=(x-2)(x+2)=x^2-4,Here a=1 and b=-4 and is not equal to -4 so a is not equal to b

Anonymous: Hence a=b is not correct and question is having problem and need correction

Anonymous: product ot of zeros=b/a,if b=a then product of zeros=1

Anonymous: So the zeros should be reciprocal of each other like m,1/m

Anonymous: qn may be: If -1/2 and -2 are the zeroes of the polynomial ax² + 5x + b, show that a = b.

Anonymous: Here product of zeros=(-1/2)(-2)=b/a

Anonymous: 1=a/b, or a=b

Anonymous: You can use factor theorem also

Answer:

If 2 and 1/2 are the zeroes of the polynomial ax² + 5x + b, show that a = b.

Step-by-step explanation:

ax² + 5x + b

product of roots

2*1/2=b/a

1=b/a

b=a
