Simplify

1. 4x-5y+3x+6y

   • 1.Collect like terms
   • 2.Add them together
   • 3.Write answer
   • = 7x+y

2. 3x^2-6x+4-2x^2+3x-3

   • 1. Collect like terms, (x^2 is not the same as x)
   • 2. Add them together
   • 3. Write answer
   • = x^2-3x+1

3. 3(a+b^2) - 2(3a-4b^2)

   • 1. Expand brackets
   • 2. Collect like terms
   • 3. Add them up
   • = -3a+11b^2

4. x^2 (times) x^5

   • 1. Times indices means add
   • 2. 2+5
   • = x^7

5. b^4/ b^4

   • 1. Divide means subtract
   • 2. 4-4
   • 3. b^0
   • = 1
