True
Answer:
Quadratic Equations! Yes!
Step-by-step explanation:
Now, there are three methods to solving this:
1.Quadratic Formula
2.Factoring
3. Completing the square
Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.
So, Quadratic Formula! To solve it using this method, we have to find x using this:
(the +- before the square root means it could be both positive or negative)
Where a, b are coefficients and c is a term(in a quadratic equation form:
)
So, we just have to input the stuff from our equation into the formula!

Now, we can simplify the square root of 32 into 4 times the square root of 2

And, we can divide 2 from it all!

So, there you have it! The Answer is C, or 3.
Hope this helps!
So each of Colise vases have 15 roses in them so she has a total of 30 roses 20 red and 10 yellow. Michelle also has 30 roses but he has three vases, each with 6 red roses, 6 x 3 is 18 and 30 - 18 is 12, 12/3 is 4 so Michelle would have 4 yellow roses in each of her vases.
Would assume it to be 36x² - 25 = 0
<span>36x² - 25 = 0
</span>
<span>(6x)² - 5</span>²<span> = 0</span>
(6x + 5)(6x - 5) = 0 By difference of two squares.
6x + 5 = 0 or 6x - 5 = 0
6x = -5 6x = 5
x = -5/6 x = 5/6
x = +5/6 or - 5/6
