D 59. Simple use of order of operations were needed.
Answer:
Step-by-step explanation:
hello :
f(x)=3x^2-6x+13
1) a=3 and b= -6
2) the x coordinate of the vertex is : x= -b/2a so : x= -(-6)/6 = 1
3) the y coordinate by x= 1 is : f(1) = 3(1)²-6(1)+13 = 10
Simplify the following:
x/((x - 2) (x + 9) (3 x - 6))
Factor 3 out of 3 x - 6:
x/(3 (x - 2) (x - 2) (x + 9))
Combine powers. x/((x - 2) (x + 9)×3 (x - 2)) = (x (x - 2)^(-1 - 1))/((x + 9)×3):
(x (x - 2)^(-1 - 1))/(3 (x + 9))
-1 - 1 = -2:
Answer: (x (x - 2)^(-2))/(3 (x + 9))
