Question

find the discriminant of equation 4x^2+3x+5=0​

Answer 1

Answer:

-71

Step-by-step explanation:

4x²+3x+5=0

b²-4ac=3²-4*4*5

= 9-80

=-71

Answer 2

Given

we have given a quadratic equation 4x²+3x+5=0

To find

We have to find the discriminant of the equation.

Solution

Discriminant is given by "D"

Formula to find discriminant :-

D = b²-4ac

From equation

a= 4

b= 3

c = 5

Now, put the values into formula:

D = 3²-4(4)(5)

D= 9-80

D= -71

The discriminant of the given equation is -71

More information=>

• If the discriminant of a quadratic equation is greater than zero ( positive) then the quadratic equation have two real and distinct solutions.
• Similarly if the value of the discriminant is less than zero ( negative) then there will be no real solutions .
• If the discriminant value is zero then there will be either two real and equal solutions or having one solution only .
