Solving Quadratic Equations by Factorisation

The solutions of the quadratic equation
x²-5x+6=0 are

• x=1 or x=-6
• x=3 or x=2
• x=-3 or x= 2
• x=-1 or x=6

The solution of the quadratic equation
4x²-5x-9=0 are

• x=-1 or x=9/4
• x=1 or x=9/4
• x=2 or x=3
• x=-2 or x=-3

( x - 1 ) ( x + 3 ) = 0
so, the roots are 1 and

• 0
• -1
• 3
• -3

Solve the following quadratic...
