Question

what is the value of b2-4ac for the quadratic equations x2+4x+3=0​

Answer 1

$\sf\huge\bold{Answer:}$

$\fbox{\rm 4}$

Given :

Quadratic equation : x²+4x+3=0

To find :

Discriminant (b²-4ac)

Solution :

• General Form of Quadratic equation :

→ax²+bx+c=0

• Given Quadratic equation :

→x²+4x+3=0

• Comparing both equations,we get

a=1

b=4

c=3

• Discriminant :

→D=b²-4ac

→D=(4)²-4(1)(3)

→D=16-4(3)

→D=16-12

→D=4

Hence, b²-4ac = 4 for x²+4x+3=0

Answer 2

Answer:

4

Step-by-step explanation:

Question: What is the value of b2-4ac for the quadratic equations x2+4x+3=0​

To Find: The Value of B²-4AC for the eq(n) x²+4x+3=0 .

Explanation:

We have been given a quadratic equation x²+4x+3=0 .

We have to find the value of B²-4AC for the given eq(n).

Now the value of:-

A= 1  

B= 4

C= 3

Therefore the value of  B²-4AC is equal to :-

= (4)²-4(1)(3)

= 16- 12

= 4 (which is the required answer)
