To apply the quadratic formula, the right side must be equal to 0.

Now you can apply the quadratic formula

to find the solution for w.

(The quadratic formula is highly unnecessary in this problem, however. You could easily divide all values by 2 to get w²-14w+49=0, which factors into (w-7)²=0, for which 7 is the only solution which puts a factor of the quadratic equal to 0.)
Answer:
x=1
Step-by-step explanation:
We can solve this equation using a mix of simplifying and using arithmetic on both sides:
6-4x=7x-9x+4
6-4x=-2x+4
2-4x=-2x
2=2x
1=x
x=1
The first one, because it cannot be represented as a/b.

Answer:
the marked answer (A) is correct
Step-by-step explanation:
The domain restrictions by themselves tell you the denominator of the rational function is ...
(x -3)(x +3) = x² -9 . . . . . matches only choice A
These domain restrictions will give vertical asymptotes at x=±3 if there is no cancelling zero in the numerator.
The horizontal asymptote at y=2 tells you the ratio of leading terms of the numerator and denominator polynomials must be 2. This requirement is also matched by choice A.
