Kurangkanlah
a) -8p+10q-9r dari 4p-11q-9r
b) -5(4y²-2y+8) dari 4(7y²+6y-5)

MathSolver74 A) (4p - 11q - 9r) - (-8p + 10q - 9r)
= 4p + 8p - 11q - 10q - 9r + 9r
= 12p - 21q

b) (4(7y² + 6y - 5)) - (-5(4y² - 2y + 8))
= (28y² + 24y - 5) - (-20y² + 10y - 40)
= 28y² + 20y² + 24y - 10y - 5 + 40
= 48y² + 14y + 35
