tolong jawab cepat dan jngn asal
Jawaban:
a. 3x = 4x²+5
4x²+5 = 3x
4x²-3x+5 = 0
a = 4; b = -3; c = 5
b. 3(x²+3x-1) = x²
3x²+9x-3 = x²
3x²-x²+9x-3 = 0
2x²+9x-3 = 0
a = 2; b = 9; c = -3
c. 3x-1 = 3/x
x(3x-1) = 3
3x²-x = 3
3x²-x-3 = 0
a = 3; b = -1; c = -3
d. x²-4 = 2x(x+3)
x²-4 = 2x²+6x
x²-2x²-6x-4 = 0
-x²-6x-4 = 0
x²+6x+4 = 0
a = 1; b = 6x; c = 4
