Algebra 210.7 day 1Solve Quadratic Systems
Learning Target:I can solve linear & quadratic systems of equations. [A.REI.7]
We've learned how to solve a linear system of equations using 3 methods:1. Graphing2. Substitution3. Elimination (Linear Combinations)
Let's Review:
1. Solve by graphing.y = x + 2y = -2x - 1
2. Solve using substitution.y = x + 14x + 5y = 23
3. Solve using elimination.3x + 2y = 66x + 3y = 6
What if we want to solve a linear-quadratic system?
4. -3x2 + y2 = 9 y = 2x
5. x2 + y2 = 10y = -3x + 10
6. y2 - 2x - 10 = 0x + y = -1
7. y = -2x - 5y = x2 + 6x + 7
Exit Problem: Solve the system. x2 + y2 = 17 y = x + 3
