(10x2 + 6x + 3) (2x + 3) Tolong jawab kareba bsk dikumpulkan

= (10x² + 6x +3)(2x + 3)
= (10x² × 2x) + ( 10x² × 3) + (6x × 2x) + (6x × 3) + (3 × 2x) + (3 × 3)
= 20x³ + 30x² + 12x² + 18x + 6x + 9
= 20x³ + 42x² + 24x + 9

mohon dikoreksi bila salah.

(20+6x+3)(2x+3)= (23+6x)(2x+3) =46x+69+12x pangkat 2 + 18 = 12x pangkat dua + 64x + 69
