Question

The discriminant of the equation 7√3x²+10x-√3 is...... plzz i need it fast

Answer 1

Explanation:

Hey there!

Here,

The equation is:

`7 √(3 \: ) {x}^(2) + 10x - √(3 ) = 0`

Comparing the equation with ax^2+bx+c=0. We get;

`a = 7 √(3)`

`b = 10`

`c = √(3)`

Now,

Discriminant= ?

We have,

`discriminant = {b}^(2) - 4ac`

Put all values.

`discriminant = {10}^(2) - 4 * 7 √(3) * √(3)`

`discriminant = 100 - 4 *7 * 3`

`discriminant = 100 - 84`

Therefore the discriminant = 16.

Hope it helps...
