If the discriminant of a quadratic equation is equal to -8, which statement describes the roots? a. there are two complex roots. b. there are two real roots. c. there is one real root. d. there is one complex root.

A.

Step-by-step explanation:

A negative discriminant (b^2 - 4ac) means there are 2 complex roots. In the formula for the roots the square root of the determinant is taken and  there is no real square root of a negative.

explanation:

he is often referred to as a man of twists and turns

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
