Question

choose the correct answer from the following:
STATEMENT A : If b(square)-4ac >0 , then the roots of the quadratic equation are real numbers.
STATEMENT B : If b(square)-4ac<0 , then roots of quadratic equation are not real numbers.

(1) . A and B are true .
(2) . A is true , and B is false .
(3) . A is false , and B is true .
(4) .A and B are false .​

Answer 1

Answer:

1

Step-by-step explanation:

we all know the the formula for finding the root of the quardratic equation x= (-b +-√b^2-4ac)/2a

so if b^2-4ac>0 then the square root of a positive number will be real and hence there will be real roots of the equation.

If b^2-4ac<0 then the square root of a negative number will be imaginary and hence there will be imaginary roots of the equation.
