Step-by-step explanation:
please mark me as brainlest
Start with y = 2x. Subst. a for x and a+sqrt(3) for y:
a+sqrt(3) = 2a
Subtracting a from both sides: sqrt(3) = a
The quardratic equation is ax^2+bx+c=0
10x^2-19x+6=0
where a=10,b= - 19 c=6
quadratic formula=

u solve it now
Answer:

Step-by-step explanation:
The given equation is
...........(i)
we know the formula i.e.

Applying this formula on equation (i) gives
= 
Opening the sqaure gives and canceling
with 2 gives us
= 
= 
which is the answer
The second number of each ordered pair for g(x) is 2 less than that for f(x).
The value of k is -2.
