Chapter 8: Q 175 (page 953)

Find the LCD of $\frac{2}{3 d^{2} + 14 c - 5}, \frac{5 d}{3 d^{2} - 19 d + 6}$ .

Short Answer

Expert verified

The LCD is $(3 d - 1) (d - 6) (d + 5)$ .

Step by step solution

Given Information

The given expression is $\frac{2}{3 d^{2} + 14 c - 5}, \frac{5 d}{3 d^{2} - 19 d + 6}$ .

Factor the denominator of both expressions.

The factored form of first denominator.

$3 d^{2} + 14 c - 5 = (3 d - 1) (d + 5)$

The factored form of second denominator.

$3 d^{2} - 19 d + 6 = (3 d - 1) (d - 6)$

Determine the common factors and from the remaining factors, multiply each of the denominator with appropriate factors.

The common factor is $(3 d - 1)$ .

Multiply common factor with other factors.

$= (3 d - 1) (d - 6) (d + 5)$
