2SIMPLIFYING EXRESSIONSSometimes “real world” applications do not always apply.This week’s assignmentcharacterizes three different equations.All of which use thedistributive propertyto solve theequation.Using thedistributive propertyremoves the parenthesis from the equation. Bycombininglike terms,after removing the parenthesis, we can retrieve thesimplifiedanswer. Byusing following each step and showing my work, you then would understand how to simplifyexpressions by using thedistributive property.2a(a-5)+4(a-5)Distributive propertyremoves the parenthesis2a2-10a+4a-20Combinelike terms2a2-6a-20Simplifieddue to no morelike termsIn this equation thecoefficientisthe 2 at the beginning of the equation. First you startwith thecoefficientand multiply 2a by both the (a-5), than you multiply the 4 by the same (a-5).By doing this first ofdistributive propertysets you up for the next part, combininglike terms.
