Sagot :
Answer:
1. x² - 6x - 7 = 0
a= 1
b= -6
c= -7
2. SF = x² - 64 =0
a= 1
b= none
c= -64
3. SF = 9x² - 2x + 8 = 0
a= 9
b= -2
c= 8
4. SF = x² - 3x - 10 = 0
a= 1
b= -3
c= -10
Answer:
1. x² - 6x - 7 = 0
a = 1, b = -6, c = -7
2. x² - 64 = 0
a= 1, b = 0, c = -64
3. 9x² - 2x + 8 = 0
a = 9, b = -2, c = 8
4. x² - 3x - 10 = 0
a=1, b= -3, c= -10
5. 4x² - 2 = 0
a=4, b= 0, c=-2
6. 2x² + 2x = 0
a= 2, b= 2, c= 0
7. x² + 8 + 16=0
a=1, b=8, c=11
8. 3x² + 5x + 9 = 0
a=3, b=5, c=9
9. x² - 4x - 66 = 0
a= 1, b=-4, c=-66
10. x² + 4 = 0
a=1, b=0, c= -4
