SIMPLIFYING EXPRESSIONS 2Simplifying ExpressionsSimplifying expressions can be found in many areas of work today. In this assignment, I am asked to use the properties of real number so simplify 3 expressions, demonstrate how I got my solution, explain why the properties of real numbers are important to know and incorporate five vocabulary words into my paper.The first given expression: 2a(a-5) + 4(a-5)2a(a)- 2a(5)+ 4(a) + 4(5)Left distributive property of addition over multiplication2(aa)-2a(5)+4(a)+4(5) Associate property of multiplication 2(aa)-2(5)a+4(a)+45Commutative property of multiplication 2(aa)-(2*5)a+4(a)+4(a)+4(5)Associate property of multiplication - 2a^2-10a+4a+20Multiplication property 2a^2-6a+20Subtraction property On the right side, I did a step-by-step of the expression 2a(a-5)+4(a-5, which was simplified as 2a^2-6a+20. The step-by-step logical reasoning can found on the right hand side.
