F(x) = -7x^2+8x+2 what is the value of the discriminant of f

D = 120,    there are 2 real roots for F(x)

Step-by-step explanatU

using the

formula  D = b^2 - 4ac  for discriminant

D =  8^2  - 4*(-7)*2

D = 64  + 56  =  120

120

Step-by-step explanation:

The discriminant can be written as an expression: b² - 4ac.

We know that a = -7, b = 8, c = 2, since the function f(x) = -7x² + 8x + 2 is in standard form: ax² + bx + 2.

Now let's evaluate the discriminant:

b² - 4ac

= 8² - 4(-7)(2)    (Simplify)

= 64 - 4(-14)

= 64 + 56

= 120

yes because they have the same amount of green and blur marbles.
