For the expression:

(9x^2 + 4y^2 -12xy) / (4y^2 - 9x^2)

Find the domain
Find the domain of the simplified expression

Answers

Answer 1

The domain of an expression is the set of input values the expression can take

The domain of the expression is [tex]y \ne 1.5x[/tex]The domain of the simplified expression is [tex]y \ne -1.5x[/tex]

(a) The domain of the expression

The expression is given as:

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)}[/tex]

Set the denominator to 0, to determine the domain

[tex](4y^2 - 9x^2) = 0[/tex]

Remove brackets

[tex]4y^2 - 9x^2 = 0[/tex]

Add 9x^2 to both sides

[tex]4y^2 = 9x^2[/tex]

Divide both sides by 4

[tex]y^2 = 2.25x^2[/tex]

Take positive square roots of both sides

[tex]y = 1.5x[/tex]

Hence, the domain of the expression is [tex]y \ne 1.5x[/tex]

(b) The domain of the simplified expression

The expression is given as:

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)}[/tex]

Rewrite as:

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(9x^2 - 12xy+ 4y^2 )}{((2y)^2 - (3x)^2)}[/tex]

Expand the numerator

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(9x^2 - 6xy - 6xy+ 4y^2 )}{((2y)^2 - (3x)^2)}[/tex]

Factorize the numerator

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{3x(3x - 2y) - 2y(3x- 2y )}{((2y)^2 - (3x)^2)}[/tex]

Factor out 3x - 2y

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(3x - 2y)(3x- 2y )}{((2y)^2 - (3x)^2)}[/tex]

Express the denominator as a difference of two squares

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(3x - 2y)(3x- 2y )}{(2y - 3x)(2y + 3x))}[/tex]

Rewrite as:

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{-(2y - 3x)(3x- 2y )}{(2y - 3x)(2y + 3x))}[/tex]

Cancel out the common term

[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{-(3x- 2y )}{(2y + 3x)}[/tex]

Set the denominator to 0, to determine the domain

[tex]2y + 3x= 0[/tex]

Subtract 3x from both sides

[tex]2y= -3x[/tex]

Divide both sides by 2

[tex]y= -1.5x[/tex]

Hence, the domain of the simplified expression is [tex]y \ne -1.5x[/tex]

Apple is the most ethical company in al of Silicon Valley

I know because I have owned a privacy/security consulting company in Silicon Valley for over 40 years so I worked with all those high tech companies and I know that Apple actually is ethical, from personal experience, the other companies don't care about ethics, they only clean up their messes when they get caught or are about to get caught doing something unethical.
