P(x)= (x²-x-2).h(x) + (5x-7)
P(x)= (x-2)(x+1).h(x) + (5x-7)
P(2) = 5.2-7 = 3
P(-1) = 5.-1-7 = -12
P(x)= (x+2).h(x) + (-13)
P(-2) = -13
P(x)= (x²-4).h(x) + (ax+b)
P(x)= (x-2)(p+2).h(x) + (ax+b)
P(2) = 2a+b = 3
P(-2) = -2a+b = -13 +
2b = -10
b = -5
2a+(-5) = 3
2a = 8
a = 4
jadi sisanya 4x-5
semoga membantu yaa.. ^_^
P(2) = 5(2)-7 = 3
P(-1)= 5(-1)-7 = -12
P(x) : x+2 bersisa -13
P(-2) = -13
P(x) : (x²-4) bersisa => ax+b
2a+b = 3
-2a+b = -13
-----------------(-)
4a = 16
a = 4
2(4)+b = 3
b = 3-8
b = -5
jadi sisanya = 4x-5
