Use the discriminant to describe the roots of each equation. then select the best description. 16x2 + 8x + 1 = 0 double root real and rational roots real and irrational roots non-real roots

Δ = 0 so we have a double root (answer A).

Step-by-step explanation:

If a quadratic equation is defined as, then the discriminant of the equation is

If D>0, then the equation has two real roots, it may be rational or irrational.

If D=0, then the equation has one real root.

If D<0, then the equation has no real roots and 2 complex roots.

The given equation is

Here, a=16, b=8 and c=1.

The value of the discriminant is

The value of the discriminant is 0, it mean the given equation has two same real root or double root.

Therefore the correct option is 1.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

correct answer is c. just did it
