1. im stuck at multiplying out brackets
how would i do this
3(a-4)
2. Think it might be 3a-12

3. You need to multiply everything in the bracket by 3.

so you would do 3 x a = 3a AND 3 x -4 = -12 (Negatice number so - as different signs make a negative)

so 3a - 12
4. 3(a-4) just basically multiply each term inside the bracket by 3 and then combine like terms (if applicable)
