Question

Selesaikan persamaan kuadrat berikut dengan memfaktorkannya!
yg i dan j no .2

Answer 1

X/4 - (2x - 1)/(x + 1) = 1
=> x/4 - (2x - 1)/(x + 1) = 1
=> (x(x + 1) - 4(2x - 1)) / 4(x + 1) = 1
=> x^2 + x - 8x + 4 = 4(x + 1)
=> x^2 - 7x + 4 = 4x + 4
=> x^2 - 11x = 0
=> x(x - 11) = 0
=> x = 0 atau x = 11

1/x + 1/4 = 3/(x + 2)
=> (4 + x)/4x = 3/(x + 2)
=> (4 + x)(x + 2) = 4x . 3
=> 4x + 8 + x^2 + 2x = 12x
=> x^2 - 6 x + 8 = 0
=> (x - 4)(x - 2) = 0
=> x = 4 atau x = 2
