Expanding and Factorising
Cards in this deck (7)
- 1Expand this expression: 5(2x+3)1. 5 (times) 2x = 10x
2. 5 (times) 3 = 15
3. = 10x +15 - 2Expand and Simplify 9(x-2)1. 9 (times) x = 9x
2. 9 (times) -2 = -18
3. = 9x - 18 - 3Expand -3y(4 -3y)1. -3y (times) 4 = -12y
2. -3y (times) -3y = +9y
3. = -12y + 9y - 4Expand 4x(x+3) -2x(3x-7)1. 4x (times) x =4x^2
2. 4x (times) 3 = 12x
3. -2x (times) 3x = -6x
4. -2x (times) -7 = +14x
4. = 4x^2 +20x - 5Factorise 3x + 91. Divide by common value = 3
2. Place remainder of values into brackets
3. 3(x+3) - 6Factorise 3x^2 - 9xy1. Divide by 3x
2. 3x(x-3y) remaining values
3. Cannot be Simplified any further - 7Factorise 10y^2 - 5y1. Divide by 5y
2. 5y(2y - 1) remaining values
3. Cannot be simplified further
