Question

Pemfaktoran

(3 + 4m)^2

(-2a + b)^5

Answer 1

Mgkn sprti ini jwbnnya
(3+4m)^2 = 3^2 + 2.3.4m + (4m)^2
= 9 + 24m + 16m^2
= 16m^2 + 24m + 9
(-2a + b)^5
= (-2a)^5 + 5.(-2a)^4(b) + 10(-2a)^3(b)^2 + 10(-2a)^2(b)^3 + 5.(-2a)(b)^4 + b^5
= -32a^5 -80a^4b -80a^3b^2 +40a^2 b^3 -10ab^4 + b^5
= -32a^5 -80ab(a^3-a^2b)-10ab(-4ab^2+b^3) + b^5
