Tlong dong bantu jawab soal no 6 ini dgn jalannya ya
whongaliemx² - (a + b)x + a.b = (x - a) (x - b) P(x) = + + (x - c) habis dibagi (x -a)(x - b) maka P(a) = 0 + + (a - c) = 0 0 + + (a - c) = 0 + (a - c) = 0 { + (a - c) = 0 + (a - c) = 0 = - (a - c) ..... pers i P(b) = 0 + + (b - c) = 0 + (b - c) = 0 . ((b - a) + (b - c) = 0 subtitusikan pers i - (a - c) (b - a) + (b - c) = 0 - (a - c) (b - a) = - (b - c) (a - c) (b - a) = b - c ab - a² - bc + ac = b - c ab - bc - b = - c - ac + a² b( a - c - 1) = - c - ac + a² b = b = b =

mksih bnyak kk.klo bsa jwab yg pnya ku yg laen jg ya :)
P(x) =
P(a) = 0
0 +
{
P(b) = 0
- (a - c) (b - a) + (b - c) = 0
- (a - c) (b - a) = - (b - c)
(a - c) (b - a) = b - c
ab - a² - bc + ac = b - c
ab - bc - b = - c - ac + a²
b( a - c - 1) = - c - ac + a²
b =
b =
b =
