Let a = –5, b = –2, and c = –4.

(-4--2)^2 + (-5)^2

(-4+2)^2 + (-5)^2

(-2)^2+ (-5)^2

Divide the expressions:<br> x + 1 / x + 2 ÷ 3x / x − 4.

slavikrds [6]

Answer:

Remember, $\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}*\frac{d}{c}=\frac{a*c}{b*d}$

Then,

$\frac{x+1}{x+2}\div\frac{3x}{x-4}=\frac{x+1}{x+2}*\frac{x-4}{3x}=\frac{(x+1)(x-4)}{3x(x+2)}=\frac{x^2-3x-4}{3x^2+6x}$ ,

Now, using long division of polynomies we have that

$\frac{x^2-3x-4}{3x^2+6x}=\frac{1}{3}-\frac{5x+4}{3x^2+6x}$
