5. f(x) = x2+3x+2
x2+3x+2 = 0
(x+2) (x+1) = 0
x+2=0 x+1=0
x= -2 x= -1
Therefore, the zeros are -2 and -1

8. f(x) = x2-5x+6
x2-5x+6 = 0
(x-3) (x-2) = 0
x-3 =0 x-2=0
x= 3 x= 2
Therefore, the zeros are 3 and 2

11. f(x) = x2-2x-3
x2-2x-3 = 0
(x-3) (x+1) = 0
x-3 =0 x+1=0
x= 3 x= -1
Therefore, the solutions are 3 and -1

13. Find the zeros of the ff. Quadratic
Functions.
1. F(x) = x2 - 5x – 24
2. F(x) = x2 – 2x -8
3. F(x) = x2 + x – 2
4. F(x) = 3x2 + 9x – 12
5. F(x) = 2x2 + 15x - 8

14. Assignment:
Find the zeros of the ff. Quadratic Functions.
1. F(x) = x2 – 3x - 4
2. F(x) = x2 +5x - 6
3. F(x) = 6x2 -9x - 15
4. F(x) = x2 - 100
5. F(x) = 81x2 – 90x + 25
