Question

Find the nature of roots of equations 9x square+12x+4=0

Answer 1

Answer:

Here is your answer

9^x2+12x+4= 0

discriminant (D) =b^2-4ac

= 12^2-4×9×4

=144-144=0

here D = 0

so equation has equal roots

hope this is true and helpful to you.

Answer 2

The nature of roots are equal.

Step-by-step explanation:

Consider the provided Quadratic equation.

Quadratic equation $9x^2+12x+4=0$

We need to determine the nature of roots of equations

Using discriminant method to determine the nature.

$D=b^2-4ac$

In quadratic equation $9x^2+12x+4=0$

Here a=9 , b=12 and c=4

Substitute in the formula,

$D=(12)^2-4(9)(4)$

$D=144-144$

$D=0$

As the discriminant is zero.

So, roots are equal.
