Answer 2

Answer:

$\Huge \boxed{(c-d)(3a+7b)}$

Step-by-step explanation:

$\bigstar \Huge\boxed{\textnormal{Subject: Math}}\bigstar$

To solve this problem, first you have to use distributive property of $\displaystyle a(b+c)=ab+ac$.

First, factor it out by the common term of 3a.

$\displaystyle 3a(c-d)+7bc-7bd$

Rewrite the problem down.

$\displaystyle 7bc-7bd$

Next, factor it out by the common term of 7b.

$\displaystyle 3a(c-d)+7b(c-d)$

Then, factor it out by the common term of (c-d).

Solve.

$\displaystyle \large\boxed{(c-d)(3a+7b)}$

$\bigstar\large\boxed{\textnormal{As a result, the correct answer is \boxed{(c-d)(3a+7b)}}}}}.\bigstar.$
