OPERASI PERKALIAN ALJABAR TOLONG DIJAWAB DENGAN CARA. 1.(2a+3)(3a+5) 2.(3a+2b)(a+3b) 3.(x+2y)(2x+3y) 4.(3x+5)(2x-1) 5.(4x-3)(2x+5) 6.(5x-4)(2x-1)

1) 6a²+ 10a+9a+15 = 6a²+19a+15
2)3a²+9ab+2ab+6b²=3a²+11ab+6b²
3)2x²+3xy+4xy+6y²=2x²+7xy+6y²
4)6x²-3x+10x-5=6x²+7x-5
5)8x²+20x-6x-15=8x²+14x-15
6)10x²-5x-8x+4=10x²-13x+4

1. (2a+3)(3a+5) =6a^2+10a+9a+15 =6a^2+19a+15
2. (3a+2b)(a+3b) =3a^2+9ab+2ab+6b^2
=3a^2+6b^2+11ab
3. (x+2y)(2x+3y) =2x^2+3xy+4xy+6y^2
=2x^2+6y^2+7xy
4. (3x+5)(2x-1) =6x^2-3x+10x-5 =6x^+7x-5
5. (4x-3)(2x+5) = 8x^2+20x-6x-15 =8x^2+14x-15
6. (5x-4)(2x-1) = 10x^2-5x-8x+4 =10x^2-13x+4
