Question

2) Write the quadratic equation if the sum of its roots is -10 and product is 21.
(Use y for variable)​

Answer 1

Step-by-step explanation:

Let two roots be a and b

sum of its root -> a+b = -10

product -> ab = 21

the required equation is = x^2 - ( a+b) + ab

= x^2 - ( -10)x + 21

= x^2 + 10x +21

Answer 2

Answer:Let the two roots be alpha and beta.

Then alpha +beta = -10

And, alpha×beta=21

So, the quadratic equation will be x^2-(-10)X+21

= X^2 +10x+21
