How do you know when you have a difference of perfect squares?

Mathematics
1 answer:
Marianna [84]3 years ago
3 0

In general, a variable to any even power is a perfect square.

So for example, x² is a perfect square and so is y¹⁴.

A common made by students is not in factoring the difference of two squares, but just failing to recognise that the difference of two squares exist.

It will also help to review your perfect squares

for the numbers between 1 and 16.

Find 4 geometric means between -5 and -125.
balandron [24]

The geometric means between -5 and -125 is; 25

<h3>How to find the geometric mean?</h3>

To find the geometric mean between two numbers, we simply find the square root of the product of the two numbers.

For example, geometric mean between A and B is;

G.M = √(A * B)

Thus, geometric mean between -5 and -125 is;

G.M = √(-5 * -125)

G.M = √625

G.M = 25

There could be other geometric means between this like;

G.M = √(-5 * -45) = 15

Or GM = √(-10 * -40) = 20

What is the answer to <br>y= -2/3x-1
Ivenika [448]

Okay, standard form is Ax + By = C, where A is non-negative. This equation is in slope-intercept form (y = mx +b)

To get this equation from slope-intercept from to standard form, we must first get rid of the fraction -2/3. To do that, multiply each term in the equation by -3:

(y = -2/3x - 1)-3

-3y = 6/3x +3 (distribute the -3 to all terms)

-3y = 2x + 3 (simplify 6/3)

-2x - 3y = 3 (subtract 2x from both sides to get x and y terms on the same side)

2x + 3y = -3 (divide the entire equation by -1)

That's my final answer. Hope this helps.
