What is the form of the Difference of Squares identity?

Mathematics
1 answer:
Feliz [49]3 years ago
3 0
The difference identity of two squares can be stated as:

a² - b² = (a + b)(a -b)

i.e. the product of sum of two numbers with the difference of two numbers. This can be easily proved.

For example, Let a = 4 and b = 3

so, a² - b² = 16 - 9 = 7

a + b = 4 + 3 = 7
a - b =4 - 3 = 1

(a + b )(a - b) = 7 x 1  = 7

Thus,

a² - b² = (a+b)(a-b)

So, option C gives the correct answer

After solving the equation x^2+ 9 = 6x, Donna stated that the Fundamental Theorem of Algebra is true for this equation. However,
Georgia [21]

Answer:

Step-by-step explanation:

The Fundamental Theorem of Algebra states that the number of complex roots a polyomial has is equal to its highest exponent.  This is a squared polynomial; second degree; quadratic.  When it is factored, no matter what types of numbers you get as the solution, you will ALWAYS have 2 of them.  When this quadratic is factored, we get that x = 3 and x = 3.  That means that this is a quadratic that touches the x-axis at (3, 0).  It doesn't go through, it only touches.  We do have 2 roots, but since they're the same, we say we have a multiplicity 2 of that root.  The closest you'll come to that in your choices is A.  Apparently your text refers to multiplicity 2 as a double root.

(10)(11)<br><br> Geometry<br><br> Check Ans<br><br> 10) 5<br> 11) x = 33 y = 38 z = 109
ICE Princess25 [194]
Problem 10

You are correct. You divide 360 over the exterior angle measure to get 360/72 = 5

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

Problem 11

x = 33 is correct as this angle is an alternate interior angle pair with the 33 degree angle up top

y = 38 is correct since y+33+109 = 180 solves to y = 38. In other words: 38+33+109 = 180

z = 109 is correct. The opposite angles of a parallelogram are congruent
