Tentukan hasil perkalian dari:
a.5x²(6x-3y)
b.(2x-2)(x+5)
c.(x-5)(x²-4x+20)

Jawaban Terkonfirmasi

$5x^2(6x-3y)=30x^3-15x^2y \ \ =============== \ \ (2x-2)(x+5)=2x^2+10x-2x-10 \ \ (2x-2)(x+5)=2x^2+8x-10 \ \ =============== \ \ (x-5)(x^2-4x+20)=x^3-4x^2+20x-5x^2+20x-100 \ \ (x-5)(x^2-4x+20)=x^3-9x^2+40x-100$
