Simple Quadratic Equations with Imaginary Solutions

If the graph of a quadratic does not touch the x-axis at any point, then it has:

• 1 Real Solution

• 2 Real Solutions

• Half a Solution

• No Real Solution / Imaginary solutions

Will the following equation have an IMAGINARY answer
11x²-9x+3=0

• yes

• no

The discriminant is

• aX²  + bX  +  c

• b - 4ac

• b² - 4ac

• b² + 4ac

Solve.
  x² = √-100

• x = 10i

• x = ± 10i

• x = ±10

• x = √10

If b²-4ac is negative, the quadratic equation has:

• Two real solutions

• Two imaginary solutions

• One real solution

• No solution

Solve for x:

• x = {-3+2i, -3-2i}

• x = {7, 6}

• x = 2±i√3

• No solution

Find the solutions of the quadratic equation x^2 + 4 = 0.

• x = 1, x = -1

• x = 2, x = -2

• x = 2i, x = -2i

• x = 4i, x = -4i

Determine the solutions of the equation 4x^2 + 16 = 0 using square roots with imaginary numbers.

• x = ±2i

• x = ±8i

• x = ±6i

Solve for x: 

• x = {-4, -1}

• x = {-1, -4}

• x = {2+i, 2-i}

• x = {-2+i, -2-i}

If the discriminant is negative, then the quadratic has:

• Real Solution
