Simplifying Expressions Activity Combining Like Terms Distributiveо Welcome to an intro to combining like terms with mr. j! need help with simplifying expressions by combining like terms? you're in the right place!whether you. Simplify: 5( − 2a 5b) − 2c. solution: apply the distributive property by multiplying only the terms grouped within the parentheses by 5. figure 2.2.1. answer: − 10a 25b − 2c. because multiplication is commutative, we can also write the distributive property in the following manner: (b c)a = ba ca. In algebra, we use the distributive property to remove parentheses as we simplify expressions. for example, if we are asked to simplify the expression [latex]3\left(x 4\right)[ latex], the order of operations says to work in the parentheses first. but we cannot add [latex]x[ latex] and [latex]4[ latex], since they are not like terms. Why don't you give it a try. 1) eliminate the 1st set of parentheses by multiply 3 with both the 5x and the 6. 2) eliminate the 2nd set of parentheses by multiplying 4 with both the 7x and the 2. 3) you will now have 4 terms. combine the like terms. your answer should have 2 terms.

Example 4. use the distributive property to combine like terms (if possible) in each of the following expressions: (a) −5 x2 − 9 x2, (b) −5 ab 7 ab, (c) 4 y3 − 7 y2, and (d) 3 xy2 − 7 xy2. solution. if the terms are “like terms,” you can use the distributive property to “factor out” the common variable part. Matching signs = positive. negative × negative = positive. positive × positive = positive. ★combine like terms. positives and negatives are addition and subtraction. like terms match in both variable and exponent. so…. to combine like terms means merge matching terms, keeping the dominant ± sign…. ★an absolute value.
