Bài 12: Tam thức bậc hai là đa thức có dạng f(x) = ax2+ b x + C với a, b, c là hằng, a  0. Hãy xác định các hệ số a, b biết f(1) = 2; f(3) = 8

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

f is the midpoint of

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
