Simplifying Expressions 2Simplifying ExpressionsIn this week’s assignment I explored simplifying expressions. These problems represent the distributive, commutative, and associative properties, and are the type of mathematical equationsthat I will see in future math classes. Knowing how to properly solve these equations will help me in my future math classes, but could also help in some scientific based classes as well. The following problem starts out with me using the distributive property for the first step:1.)2a(a – 5) + 4(a – 5) I used distributionin this step; multiplied the coefficientby the values within the parenthesis; same with 4 on the opp. side2a2 – 10a + 4a-20 The previous step caused for me to remove the parenthesis. In this step I combined like terms.
