Persamaan Kuadratik

Bentukkan persamaan kuadratik
Form a quadratic equation
(8 + h)(2h - 7) =

• 2h² - 9h + 56
• 2h² + 9h - 56
• h² + 9h + 56
• 2h² + 8h - 56

Selesaikan persamaan kuadratik
Solve the quadratic equation
2k² + 9k + 4 = 0

• (x + 1)(x - 4) = 0
• (2x - 1)(x - 4) = 0
• (2x + 1)(x + 4) = 0
• (x + 3)(x + 4) = 0

Solve the quadratic equation
x(2x + 5) = 3
2x² + 5x - 3 = 0 

• (2x -1)(x - 3) = 0
  x = 0.5, x = 3
• (2x + 1)(x + 3) = 0
  x = -0.5, x = -3
• (2x + 5)(x + 3) = 0
  x = -5/2,  x = -3
• (x + 3)(2x - 1) = 0
  x = -3, x = 0.5

Cari nilai-nilai p jika persamaan
x² + 4x + 13 = p ( 2 - x )
mempunyai dua punca yang sama

• p = -18 ,  p = - 2
• p  -18,  p = 2
• p = 6, p = -6

Diberi persamaan kuadratik x² + 3x - 18 = 0. Cari nilai-nilai x.

• x = 3, x = 6
• x = 3, x = -6
• x = -3, x = 6
• x = -3, x = -6
