(15×pangkat 2-20×):5×=……

Jawaban:

$(15 {x}^{2} - 20x) div 5x = \ \ frac{15 {x}^{2} - 20x}{5x} = \ \ frac{15 {x}^{2} }{5x} - frac{20x}{5x} = \ \ ( (15 div 5) times ( {x}^{2} div x)) - ((20 div 5) times (x div x)) = \ \ (3 times {x}^{2 - 1} ) - (4 times {x}^{1 - 1} ) = \ \ (3 times x) - (4 times {x}^{0} ) = \ \ 3x - (4 times 1) = \ \ = 3x - 4$
