Solve for x:
1. x² = 49
2. 33 = x² - 3
3. x² + 2 = 0
4. 2 = x² - 6
5. x² = 81
Solve by Factoring:
1) x² - 5x + 6 = 0
2) x² - 9 = 0
3) x² + 2x + 2 = 1
4) x² - 4x = -4
5) x² + 5x + 25 = 20
Solve by Completing the Square:
1) x² + 6x + 9 = 0
2) x² + 8x - 5 = 0
3) x² + 6x = 8
4) 3x²- 3x + 4 = -6
5) x² + 2x - 6 = 87
Solve by Using the Quadratic Formula:
1) 2x² + 4x - 9 = 0
2) x² - 3x + 7 = -2
3) x² = 9
4) 4x² + 6x - 7 = 0
5) 2x² - x + 3 = 0
Graph:
1) x² + x + 6 = 0
2) x² + 3x - 18 = 0
3) x² = 16
4) x² - 4x + 6 = 2
5) 2x² + x - 3 = 0
Solve Using the Method of Your Choice:
1) 3x² - x - 2 = 5y
x² + x - 1 = -4y
2) x² + 3x - 4 = y
2x² + 4x - 1 = 3y
3) 4x² - 5x - 3 = 2y
-x² + x - 4 = 2y
4) x² - 6x + 4 = 4y
-(x/2) + 3x - 6 = -12y - 12x + 2x²
5) -2x² - 4x + 1 = -4y
5x² - 4x - 1 = -2y
Congratulations! You have beaten Mr. Linear. You are no longer confined to a straight, plane, boring world.
