2)Find the value of discriminant of 7x2 + 8x -10​

Answer 1

Step-by-step explanation:

a=7 b=8 c=-10

Discriminant=b^2-4ac

=8^2-4*7*-10

= 64-(-280)

=344

Answer 2

Question:

• Find the value of discriminant of 7x2 + 8x -10

Equation:

• 7x²+8x-10

solution :

As equation is

7x²+8x-10

So ,

a= 7

b= 8

c= -10

Discriminant = b²-4ac

[ Putting value of a , b and c]

Discriminant = (8)²-4(7)(-10)

=64-(-28)(10)

= 64-(-280)

=64+280

= 344

So, the value of discriminant = 344
