Question

Which represents the solutions of the graphed system of equations, y=x^2-2x and y=-2x-1

Answer 1

Answer:

No real roots.  Imaginary roots would be x = plus or minus i .

Step-by-step explanation:

Eliminate y for now by equating y=x^2-2x and y=-2x-1.  Then:

x^2 - 2x = -2x - 1

Add 2x to both sides.  Then x^2 = -1.

This is NO SOLUTION, since the square root of -1 would be imaginary.
