Q. Simplify the expression. Write your answers using integers or improper fractions.21(23q−5q−5)−3qAnswer:
Write Expression: Write down the expression to be simplified.(21)((23)q−5q−5)−3q
Distribute (1/2): Distribute the (1/2) across the terms inside the parentheses.(1/2)(3/2)q−(1/2)(5q)−(1/2)(5)−3q
Simplify Each Term: Simplify each term. 43q−25q−25−3q
Combine Like Terms: Combine like terms. To combine the terms with q, we need a common denominator. The common denominator for 4 and 2 is 4.43q−410q−25−3q
Combine Q Terms: Combine the q terms.(43)q−(410)q is (−47)q.Now we need to convert −3q to a fraction with a denominator of 4 to combine it with (−47)q.−3q is the same as (−412)q.(−47)q−(412)q is (−25)
Combine Q Terms: Combine the q terms with a common denominator.(−47)q−(412)q is (−419)q.Now we have (−419)q−(25).
Convert to Fraction: Convert (25) to a fraction with a denominator of 4 to combine it with (−419)q.(25) is the same as (410).(−419)q−(410)
Combine Constant Terms: Combine the constant terms. (−419)q−(410) is the simplified expression.
