CF3i - Simplifying Expressions (Subtraction & Division)

Changing "-" to "+ ^{-}".Then distribute or share the "-" into the "( )" Option #1There are two approaches to simplify expressions involving subtraction: Try out the Plus-Change-Change rule by dragging and dropping your selections from left to right Option #2 Use the "Plus-Change-Change" rule (4m + 3) - ( ^{ }m + 5)(4m + 3) ( ^{ }m + 5)+ ? - ? - ? The "Plus-Change-Change" rule After applying the P-C-C rule, drop the parenthesis and combine like terms to complete the problem Most students favor the "Plus-Change-Change Rule. (4m + 3) + ( ^{-}m + ^{-}5)4m + 3 + ^{-}m + ^{-}5+ Type in your answers (4m + 3) - ( ^{ }m + 5)(4m + 3) + ( ^{-}m + ^{-}5)(9n + 10) - ( 3n + 7) (9n + 10) ( 3n + 7) Now drop the parenthesis and combine like terms Now let's see if we can put it together. Completely simplify the following expression Drag & drop you selection, then type in your answers Apply the Plus-Change-Change Rule + ? + - ? - ? (15n + 1) - ( 5n + 8) (15n + 1) ( 5n + 8) Now drop the parenthesis and combine like terms Let's try another one. Completely simplify the following expression. Apply the Plus-Change-Change Rule Drag & drop you selection, then type in your answers + ? + - ? - ? (20n + 6) - (11n - 4) Try this one on your own. Completely simplify the following expression. Type in your answers + Share the division to each term in the numerator, then simplify each new term separately. Option #19n + 12p + 18 39n + 12p + 18 3 3 33n + 4p + 6 Now let's try simplifying expressions involving division: Group them using ovals, then simplify each term contained in each oval. Option #23k + 4j + 8 Let's try a couple problems using option #1. Completely simplify the given expression. Share the division to each term in the numerator, then simplify each new term separately. Option #18a + 24b + 32 4+ + Type in your answers 9n + 12p + 18 39n + 12p + 18 3 3 33n + 4p + 6 + + Completely simplify the given expression. 24x + 32y + 80 8+ + Type in your answers + + Completely simplify the given expression. 14s - 28t + 49 7- Type in your answers + Completely simplify the given expression. 30p + 60q - 45 5+ Type in your answers - |
