(iv) Expand (2x+1)^2. Step 1: Tumia fomula ya kupanua binomial iliyopigwa mraba: (a+b)^2 = a^2 + 2ab + b^2. Hapa, a=2x na b=1. (2x+1)^2 = (2x)^2 + 2(2x)(1) + (1)^2 Step 2: Rahisisha kila neno. (2x)^2 = 4x^2 2(2x)(1) = 4x (1)^2 = 1 Step 3: Unganisha maneno yaliyopatikana. (2x+1)^2 = 4x^2 + 4x + 1 Kupanua (2x+1)^2 kunatoa 4x^2 + 4x + 1. (v) Comment on the expressions obtained in (iii) and (iv). Katika sehemu (iii), eneo la mraba lenye pande (2x+1) units lilipatikana kuwa 4x^2 + 4x + 1. Katika sehemu (iv), tulipanua usemi (2x+1)^2 na tukapata 4x^2 + 4x + 1. Maoni: Maneno yaliyopatikana katika sehemu (iii) na (iv) ni sawa. Hii inathibitisha kwamba eneo la mraba lenye urefu wa upande (2x+1) units linaweza kuwakilishwa kama (2x+1)^2, na kupanua usemi huu kunatoa eneo la 4x^2 + 4x + 1. Hii inaonyesha uhusiano kati ya jiometri (eneo la mraba) na aljebra (upanuzi wa binomial). Umefanya vizuri! Tuma swali linalofuata 📸
