MATHEMATICS FORM 4 KSSM

Which of the following is a statement ?

• 3 + 8

• x² - 5x +6

• 4² = 8

• x - 6 = 10

6t²-9t-6 =

• 3(2t - 1)(t + 2)

• 3(2t + 1)(t - 2)

• (2t - 1)(t - 2)

• (2t + 1)(t - 2)

 $\frac{x^2+2}{2}+\frac{x^2}{3}=x$  

•  $5x^2-6x+6=0$  

•  $5x^2-6x-6=0$  

•  $5x^2-6x+3=0$  

•  $5x^2-6x-3=0$  

Solve the following quadratic equation...

x² + 3x + 2 = 0

• x = -1

  x = -2

• x = 1

  x = 2

• x = -1

  x = 2

• x = 1

  x = -2
