Question

Tolong bantuin, mate kls 10

Answer 1

Y = y
2x^2 - 4x - 3 = -x + 6
2x^2 - 4x - 3 + x - 6 = 0
2x^2 - 3x - 9 = 0
2x^2 - 6x + 3x - 9 = 0
2x(x - 3) + 3(x - 3) = 0
(x - 3)(2x + 3) = 0
x = 3 atau x = -3/2

Jika x = 3:
y = -x + 6
y = -3 + 6
y = 3

Jika x = -3/2:
y = -x + 6
y = -(-3/2) + 6
y = 3/2 + 6
y = 3/2 + 12/2
y = 15/2

HP = {(3,3),(-3/2, 15/2)}
