Chapter 7: Q 438 (page 737)

In the following exercise solve $\frac{3}{q + 8} - \frac{2}{q - 2} = 1$

Short Answer

Expert verified

The solution is $q = - 2 a n d q = - 3$

Step by step solution

Step 1. Given information

$\frac{3}{q + 8} - \frac{2}{q - 2} = 1$

Step 2. Solve.

The least common denominator of all denominators in the equation is $(q + 8) (q - 2)$

Clear the fraction by multiplying both sides of the equation by the LCD.

$(q + 8) (q - 2) (\frac{3}{q + 8} - \frac{2}{q - 2}) = (q + 8) (q - 2) (1) (q + 8) (q - 2) (\frac{3}{q + 8}) - (q + 8) (q - 2) (\frac{2}{q - 2}) = (q + 8) (q - 2) (1) 3 (q - 2) - 2 (q + 8) = (q + 8) (q - 2) q - 22 = (q + 8) (q - 2) q^{2} + 5 q + 6 = 0 (q + 3) (q + 2) q = - 3 o r q = - 2$
