Question

If one of the zeroes of a quadratic polynomial of the form x2 + ax + b is the negative of the other, then it: (a) has no linear term and the constant term is negative. (b) has no linear term and the constant term is positive. (c) can have a linear term but the constant term is negative. (d) can have a linear term but the constant term is positive. [NCERT Exemplar]​

Answer 1

Answer:

b)

Step-by-step explanation:

if one root is negative then the other will be positive both roots can't be negative

Answer 2

Answer:

(a) has no linear term and the constant term is negative.

Step-by-step explanation:

Let the 2 zeroes be a and -a

coefficient of x is the sum of zeroes

so,             sum = a + (-a)

                         = a-a

                         = 0

 so, it has no linear term

   then the comstant is the product of zeroes

so ,              product = a  x -a = - a^2

   so, the constant term is negative
