Applying the completing square method:
f(x) = 2x² - 8x + 6
Dividing by a
f(x) = 2(x² - 4x + 3)
Adding and subtracting the square of b (which is 2 in this case)
f(x) = 2(x² + 2² - 4x -2² + 3)
f(x) = 2(x - 2)² - 2
The vertex is (2, -2) and it is a minimum since the coefficient of x is positive.
The answer is B.
here to find the factors firstly we need to find the zeros of the function , zeros are those points at which the graph crosses or touches the x axis
Now we can see the zeros are x=4 and x=6
And we can write the factors as (x-4) and (x-6)
So the factorization would be
(x-4)(x-6)
Answer:
The expression is not factorable with rational numbers.
x² − 4x + 7
i don't really get the part after the (-4,-6) , what did u write there
