Question

True or false. Justify your answer.
Every quadratic equation has equal roots when coefficient of x is zero and constant term is negative.

Answer 1

Answer:

Write whether the following statements are true or false. Justify your answers.

(i) Every quadratic equation has exactly one root.

(ii) Every quadratic equation has atleast one real root.

(iii) Every quadratic equation has at least two roots.

(iv) Every quadratic equation has atmost two roots.

(v) If the coefficient of x2 and the constant term of a quadratic equation have opposite signs, then the quadratic equation has real roots.

(vi) If the coefficient of x2 and the constant term have the same sign and if the coefficient of x term is zero, then the quadratic equation has no real roots.

Answer 2

Answer:

false

Step-by-step explanation:

for having equal roots  in a quadratic equation $b^{2}-4ac$=0

here in the question b=0 so to satisfy  $b^{2}-4ac$=0, a should also be 0 which is $x^{2}$ coefficient, as it is given constant term is non zero.

if a and b are zeroes then it will not form a quadratic equation
