Tentukan aljabar berikut A) (x-5y) (x+5y) B) 3x²(5x-2y) C) -5(2x² -5y)

a. (x-5y)(x+5y)
= x^2+5xy-5xy-25y^2
=x^2 -25y^2

b.3x^2(5x-2y)
=15x^3 -6x^2 y (dibaca 15 xkuadrat,min 6 xkuadrat y)

c.-5(2x^2 -5y)
-10x^2 +25y

semoga membantu

A) (x - 5y) (x + 5y)
= x² + 5xy - 5xy + 25y²
= x² + 25y²
 
B) 3x²(5x - 2y)
= 15x³ - 6x²y
 
C) -5(2x² - 5y)
= -10x² + 25y
