Jawaban Terkonfirmasi
(5a+2b)+(6a-4b) = 5a+6a+2b-4b = 11a-2b
(20-16x-34y)+(3x+22y-8) = -16x+3x-34y+22y+20-8 = -13x-12y+12
(10a+7b)-(11a-9b) = 10a-11a+7b+9b = -a+16b
(-3m+4n-67)-(7n-8m-10) = -3m+8m+4n-7n-67+10 = 5m-3n-57
(a+b)(5a-10) = (a.5a)-(a.10)+(b.5a)-(b.10)
= 5a²-10a+5ab-10b
(8-3p)(b-10) = (8.b)-(8.10)-(3p.b)+(3p.10)
= 8b-80-3bp+30p
