What does factorising mean in the context of engineering mathematics?

• Putting into brackets

• Solving equations

• Multiplying terms

• Dividing coefficients

What is essential to be able to factorise an expression?

• Each term must contain a variable

• The expression must include a subtraction

• The terms outside the bracket must be exactly the same

• All terms must be divisible by the number 2

What is the result of rearranging the formula to make F the subject in Example 2?

• TF = TC + 32

• TF = (180(TC))/100 + 32

• TF = (TC - 32) * 180/100

• TF = TC * 100/180 + 32

How do you make 'x' the subject in Example 4?

• x = (5y - 6)/hy

• x = hy/(5y - 6)

• x = (5y)/(hy + 6)

• x = 5y/(hy + 6)
