F (x)=-4x^2+10x-8
What is the value of discrminant of f
How many distinct real number zeros does f have

Answer 1

2 Real Roots

Explanation:

The discriminant (D) is found using the formula b^2+4ac for the equation ax^2+bx+c.

If D>0 there are two real roots, D=0 one real root and D<0 no real roots.

D = b^2+4ac

D = 10^2+4(-4)(-8)

D = 100+32*4

D = 100+128

D = 228

since 228>0

There are 2 real roots
