Question

If the coefficient of x is zero in a quadratic polynomial then prove that the zeroes will be the equal in magnitude and opposite in sign

Answer 1

Let the quadratic polynomial be
a x^2 + bx + c.

Let the zeros be m and n

Given: b=0

Now,

Sum of the zeros = (-b/a)

i.e m+n = 0 ( since b= 0)

===> either m = -n or n = -m

Therefore the zeros are opposite in sign.
