Question

3. Write the nature of two roots of the equation 2x+ + 7x + 3 = 0.​

Answer 1

Answer:

Roots are real and positive

Step-by-step explanation:

(b²-4ac) define the nature of roots.

2x²+7x+3 =0

Comparing with standard quadratic equation ax²+bx+c =0

Here, a=2 , b=7 , c=3

Therefore,

b²-4ac

= (7)²- 4(2)(3)

= 49 - 24

= 25 > 0

=> b²-4ac >0

=> Roots are real and positive.
