Expanding brackets! help please?

Hey i have to expand some brackets. i forgot how to do it and i need to know. so could you talk me through this first one then i can do the rest?(x+6)(x-8)Thanks

Answer:

Expanding brackets in math is simply multiplying all expressions inside the bracket with the variable or coefficient outside. For example: 3x(5 + 3y) 2 To expand the brackets, simply multiply 3x with each of the expressions inside, always keeping in mind the sign of the answer (negative/positive) Step 1: (3x * 5) + (3x * 3y) 2 Step 2: 15x + 9xy 2
