Quadratic Formula #1.pdf
Using the Quadratic Formula #1
Solve each equation by using the Quadratic Formula. Write answers in reduced radical form where necessary.
1. x² - 49=0
2.x²-x-20 = 0
3.x²5x-36=0
4. x² + 11x +30=0
5.x² - 7x=-3
6. x² + 4x = -1
7. x² - 9x +22=0
8. x² + 6x + 3 = 0
9. 2x² + 5x-7=0
10. 2x²-3x = −1
11. 2x² + 5x + 4 = 0
12. 2x² + 7x = 9
13. 3x² + 2x-3=0
14. 3x² - 7x-6=0
State the value of the discriminant for each equation. Then determine the number of real solutions of the equation.
15. x² + 4x +3=0
16. x² + 2x + 1 = 0
