Question

Discrimination of Y= -4x^2+ 2x+1

Answer 1

Discriminant = 16

As 16>0, The roots will be real and unequal.

Step-by-step explanation:

The standard form of a quadratic equation is:

$ax^2+bx+c = 0$

The discriminant is calculated as:

$D=b^2-4ac$

Given equation is:

$Y=-4x^2+2x+1$

Here

a = -4

b = 2

c = 1

Putting the values

$D =(2)^2 - 4(-4)(1)\\=4+16\\=20$

The discriminant is 16 which is greater than zero so the roots of the equation will be real and unequal.
