Write each equation in the form of ax²+bx+c=0 and identify the values of a, b c. 1. x² -7x = -1
2. -3x + 2= 4x²
3. 6 + 3x²= -3x
4. 2x² = 9
5. 9x² - 5x = 5
6. 2(3x + 5) = x²
7. 3 ( x - 2)²= 6
8. 8x² + 3 = -4x
9. 2x - 3 = 2( x - 1 )²
10. 6 = ( 3x + 1 )²
11. ( x - 8)(x + 5 ) = 14
12. (x - 4)² + 8 = 0
13. (2x + 7)(x - 1 ) = 0
14. (x + 7)(x - 7) = -3x
15. 2x( x - 3) = 15
