Solve by factoring 4x^2-25=0

Mathematics
1 answer:
Ira Lisetskai [31]3 years ago
3 0
                               4x² - 25 = 0
            4x² - 10x + 10x - 25 = 0
2x(2x) - 2x(5) + 5(2x) - 5(5) = 0
          2x(2x - 5) + 5(2x - 5) = 0
                   (2x + 5)(2x - 5) = 0
       2x + 5 = 0    U    2x - 5 = 0
             - 5  - 5              + 5 + 5
             2x = -5               2x = 5
              2      2                2     2
               x = -2¹/₂             x = 2¹/₂

Solution Set: {-2¹/₂, 2¹/₂}

What is the least common multiple. Thanks.
o-na [289]

Before we start, find the LCM of 9, 5, and 5, which is 1. The least common multiple for the x is x^3, because it is the smallest exponent. The smallest multiple for y is 0, because the last factor doesn't even have y. For z, it is z^2. So your answer is 1x^3z^2, or just x^3,z^2.

Joanie watched 1 out of three of a movie in the morning
Archy [21]

Answer:

7/15

Step-by-step explanation:

Determine how much she has watched.

1/3 + 1/5 The common denominator of 3 and 5 is 15. Multiply each fraction by an amount that will make the denominator 15

1/3 = 1*5/(3*5) = 5 / 15

1/5 = 1*3 / (5*3) = 3/15

Now add the two fractions together.

5/15 + 3/15 = 8/15

What is left of the movie? The whole movie = 1 so that which is left is

1 - 8/15

15/15 - 8/15

7 / 15

She has just a bit under 1/2 to go.
