Solving Quadratic Equations by Factorising
Solve each equation using the zero-product property: factorise first if needed, then set each bracket equal to zero. Give every solution.
- 1.Solve: (x + 3)(x - 1) = 0
- 2.Solve: (x + 4)(x - 9) = 0
- 3.Solve: (x + 5)(x - 9) = 0
- 4.Solve by factorising: - 2x - 15 = 0
- 5.Solve by factorising: - 4x - 12 = 0
- 6.Solve by factorising: - 4x - 45 = 0
- 7.Solve by factorising: + 3x - 18 = 0
- 8.Solve: = 49
- 9.Solve: = 100
- 10.Solve by factorising: + 12x + 36 = 0
