MissTica

Answer:

Option B is the correct option.

Step-by-step explanation:

$- \frac{1}{2} + x = - \frac{21}{4}$

Move constant to R.H.S and change its sign:

$x = - \frac{21}{4} + \frac{1}{2}$

Take the L.C.M

$x = \frac{ - 21 + 1 \times 2}{4}$

$x = \frac{ - 21 + 2}{4}$

Calculate

$x = - \frac{19}{4}$

Hope this helps...

Good luck on your assignment..

Simplify the equation

Arturiano [62]

Answer:

$\dfrac{16x^3-37x^2-16x+37}{x^2+2}$

Step-by-step explanation:

There aren't any factors that cancel (except 3x). The best you can do is multiply it out.

$\displaystyle\frac{\frac{3x^2-3}{x}}{\frac{3(x^2+2)}{16x^2-37x}}=\frac{3(x^2-1)}{x}\cdot\frac{16x^2-37x}{3(x^2+2)}\\\\=\frac{x(x^2-1)(16x-37)}{x(x^2+2)}=\frac{16x^3-37x^2-16x+37}{x^2+2}$
