Untuk mencari koefisien \( x^{2} \) dari hasil pembagian \( 2 x^{4}-11 x^{3}+18 x^{2}-17 x+20 \) oleh \( x-3 \), kita bisa menggunakan aturan pembagian polinom. Pertama, kita akan melakukan pembagian polinom dengan metode sintetis atau long division untuk menemukan hasil bagi. Setelah melakukan pembagian, kita akan mendapatkan hasil yang berbentuk polinom, dan koefisien dari \( x^{2} \) dapat kita identifikasi. Berdasarkan perhitungan, koefisien \( x^{2} \) yang didapat dari pembagian tersebut adalah 4. Jadi, jawabannya adalah E. 4.
