Practice problem
Find all solutions to this system of equations: {y=x2+2x+1(1)y=x2+2x−1(2)\begin{cases} y=x^2+2x+1 \quad (1)\\ y=x^2+2x-1 \quad (2) \end{cases}{y=x2+2x+1(1)y=x2+2x−1(2)
(1,2),(1,4)(1, 2), (1, 4)(1,2),(1,4)
(1,2)(1, 2)(1,2)
(−1,2),(1,2)(-1, 2), (1, 2)(−1,2),(1,2)
There is no solution
Type a concept, like “slope” or “photosynthesis”.
