Question

TENTUKAN HIMPUNAN PENYELESAIAN DARI :

xlog (x+6) + xlog (x-1) = 2 + xlog2

Answer 1

Verified answer

X'log (x + 6) + x'log (x - 1) = 2 + x'log 2
x'log (x + 6)(x - 1) = x'log x² + x'log 2
x'log (x + 6)(x - 1) = x'log (x² . 2)
(x + 6)(x - 1) = 2x²
x² + 5x - 6 - 2x² = 0
x² - 5x + 6 = 0
(x - 2)(x - 3) = 0
x = 2 atau x = 3

HP = {2 , 3}
