Black question mark ​ (a)  

Blue question mark ​ (b)  

Red question mark ​ (c)  

Determine the values of a, b, and c for the quadratic equation:

4x² – 8x = 3

What types of solutions would each expression produce?

Which statement correctly describes the number and type of solutions in the equation

$$x^2=20$$

$$2x^2+8x-7=0$$

Use the quadratic formula to type an expression that will yield the solutions to the equation above.

You cannot type $$\pm$$ on the keyboard so instead put $$+-$$
