Find Imaginary Roots

If the discriminant is negative, then the quadratic has:

• 1 Real Solution

• 2 Real Solutions

• Half a Solution

• 2 Complex (imaginary) Solutions

Determine the value of the discriminant and describe the number and type roots for the following:

x² + 7x + 13

• 101, 2 real roots

• 3, 2 real roots

• -101, 2 imaginary roots

• -3, 2 imaginary roots

Q1. What is the value of x?

• A) 10

• B) -10

• C) 10i

• D) -10i

• 10
• -10
• 10i
• -10i

• i

• -1

• 1

• -i

• 5i
• -5i
• 5+i
• -5

When looking for possible imaginary/complex roots, we need to look at

• f(x)

• f(-x)

• -f(x)

• xⁿ

All imaginary roots comes in pairs.

• True

• False
