19.
) Find the nature of roots of the quadratic equation

$4x {}^{2} + 12x + 9 = 0$
​

Answer 1

Answer:

Therefore, root of the given equation 4x² - 12x - 9 = 0 are real and distinct. Hence, nature of roots of the quadratic equation 4x²− 12x − 9 = 0 are real and distinct.

Answer 2

Answer:

4x

2

+12x+9=0

4x

2

+6x+6x+9=0

2x(2x+3)+3(2x+3)=0

(2x+3)(2x+3)=0

2x+3=0

x=− 3/2

2x+3=0

x=− 3/2

x=−3/2 ,-3/2
