It would be 1/6a-1/6
You need to find the common denominator which is six
-2/3a+5/6a
-4/6a+5/6a=1/6a
The best estimate is 17/60 .
Answer:
(3+a)
Step-by-step explanation:
3a + a^2
-------------
a
Factor out an a in the numerator
a(3+a)
-------------
a
Cancel like terms
(3+a)
Answer: b and d
Step-by-step explanation:
Since the roots are x=2 and x=6, we can write the equation as

Substituting in the coordinates of the vertex,

So, the equation is 
On expanding, we get 
X + 3 * 21 = 12
x + 63 = 12
x = 12-63
x = -51
The wording was a little odd, but I hope this is what you’re looking for!
