Answer:

The answer to your question is below

Step-by-step explanation:

      -4x² + 9y² + 32x + 36y - 64 = 0

     -4x² + 32x        + 9y² + 36y         =  64                          

     -4(x² + 8x        ) + 9(y² + 4x        ) = 64                     Factor coefficients

     -4(x² + 8x + 4²) + 9(y² + 4x + 2²) = 64 - 64 + 36     Complete trinomials

                -4(x + 4)² + 9(y + 2)² = 36                              Factor trinomials

    \frac{-4(x+4)^{2} }{36} + \frac{9(y + 2)^{2} }{36} = \frac{36}{36}

                                                                                       Divide by 36

    - \frac{(x+ 4)^{2} }{9} + \frac{(y + 2)^{2} }{4} = 1   Simplify

Write the pair of fractions as a pair of fractions with a common denominator
Dmitriy789 [7]

I'll do the first two problems to get you started

Problem 1

1/2 = 3/6

1/3 = 2/6

For the first fraction, I multiplied top and bottom by 3. Note how 3 is the denominator of the second fraction.

For the second fraction, I multiplied top and bottom by 2. Note how 2 is the denominator of the first fraction.

===============================================

Problem 2

1/2 = 5/10

3/5 = 6/10

Like with problem 1, I multiplied top and bottom of the first fraction by the value 5 which is the denominator of the second fraction. Likewise, I did the same for the second fraction using the first denominator. The steps are essentially the same, but the numbers are different.

Problem 3 will be handled the same way. I'll let you try it out.
