This animation walks through simplifying (x+3)(5+y)+(x+3)(2-y) by recognizing (x+3) as a shared factor in both terms. It shows how to factor it out, combine the remaining terms inside brackets, and simplify 5+y+2-y to 7, arriving at the final simplified expression 7(x+3). Useful for students learning factoring techniques and teachers introducing common factor extraction in algebraic expressions.

Pembahasan Faktor yang sama adalah (x+3), sehingga: (x+3)(5+y)+(x+3)(2-y) =(x+3)\big[(5+y)+(2-y)\big] Sederhanakan bagian dalam kurung: 5+y+2-y=7 Jadi: =7(x+3) Jawaban \boxed{\text{A. }7(x+3)}
