Answer 1

Answer:

b) (10 , 9)

Step-by-step explanation:

●given,

addition of roots is 9

which means the roots of equation a + b = 10

●also given,

their product is 9

which means a*b = 9

now,

we know that any quadratic equation is of the form

》x^2 - (a + b)*x + (a*b) = 0

hence in the given question

the equation is

》x^2 - 10x + 9 = 0

Answer 2

Answer:

Option B - (10,9)

Step-by-step explanation:

Let the roots be α,β.

Given Sum of roots = 10.

α + β = 10   ----- (1)

Given, product of roots = 9

αβ = 9

We know that :

Required quadratic equation is :

x² - (sum of roots)x + Product of roots

⇒ x² - (10)x + 9

⇒ x² - 10x + 9 = 0
