Question

y=x^2-2x-1
y=-2

what are the solutions of the system?

asnaseer · Answer

you gave two expression for y.
just equate them to get an expression involving just x as follows:$$x^2-2x-1=-2$$then add 2 to both sides to turn this into a standard quadratic equation and solve to find the values of x.
