Perkalian a. (x+5)(x-3)=x^2-3x+5x-15=x^2+2x-15 b. (a-4)(a+3)=a^2+3a-4a-12=a^2-a-12 c.(3y-1)(y+2)=3y^2+6y-y-1=3y^2+5y-1 d.(3x-4)(2x+3)= 6x^2+9x-8x-12=6x^2+x-12

1. a. x² + 2x - 15 b. a² - a - 12 c. 3y² + 5y - 2 d. 6x² + x - 12
2. a. x² -2x b.a³-3a²b+3ab²-b² c. 2a^4 + a³ - 4a²b +2ab² - 2ab +b² d. -3a^4 + 6a³ +2a² - 10a +5
a. (x+5)(x-3)=x^2-3x+5x-15=x^2+2x-15
b. (a-4)(a+3)=a^2+3a-4a-12=a^2-a-12
c.(3y-1)(y+2)=3y^2+6y-y-1=3y^2+5y-1
d.(3x-4)(2x+3)= 6x^2+9x-8x-12=6x^2+x-12
a. x² + 2x - 15
b. a² - a - 12
c. 3y² + 5y - 2
d. 6x² + x - 12
2.
a. x² -2x
b.a³-3a²b+3ab²-b²
c. 2a^4 + a³ - 4a²b +2ab² - 2ab +b²
d. -3a^4 + 6a³ +2a² - 10a +5
