-2x^2+5x-4=0 , find the discriminant
BaLLatris [955]

Answer:

The discriminant is -7

Step-by-step explanation:

The discriminant of a quadratic function/equation(ax^2+bx+c = 0) is calculated as:

b^2 -4ac

Here

b is the co-efficient of x

a is the co-efficient of x^2

and c is the constant

Given equation is:

-2x^2+5x-4=0

Here

a = -2

b = 5

c = -4

Putting the values in the formula for discriminant

= b^2 - 4ac\\= (5)^2 - 4(-2)(-4)\\= 25 - 32\\=-7

As the discriminant is negative, the equation has no real solution.

Hence,

The discriminant is -7

Is this answer correct? Thank you
elena-14-01-66 [18.8K]
Your answer is technically correct, but you need to simplify it. Both 12 and 36 can be divided by 12. After doing that you get:
1:3
Also, you need to make sure the order is correct, 1:3 also fixes the order.
