Find the discrimanant and the number of real roots for this equation 9x^2+12x+4=0

For this case we have that by definition, the discriminant of a quadratic equation , is given by:

: Two different real roots

: Two equal real roots

: Two different complex roots

If we have , then:

Substituting the values:

Thus, we have two equal real roots.

We have two equal real roots.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
