A bag of potatoes is measured as 5kg to the nearest kg. What is the minimum and maximum weight the bag could be? 

• 4kg and 5kg

Factorise and hence solve
x² - 6x - 7 = 0 

• x = -7 and 1
• x = 7 and -1 
• x = 7 and 1 

Factorise and hence solve 
x² + 7x + 10 = 0 

• x = 2 and 5 
• x = -5 and -2 
• x = 9 and 1 
• x = -9 and -1 

Factorise and hence solve 
2x² - 10x + 8 = 0 

• x = 4 and -2 
• x = -4 and 2 
• x = -2 and -4
