Q. Combine the like terms to create an equivalent expression:−5j+(−2j)+3
Identify like terms: Identify like terms in the expression −5j+(−2j)+3.Like terms are terms that contain the same variable raised to the same power. Here, −5j and −2j are like terms, while 3 is a constant term and not like a term with j.
Combine like terms: Combine the like terms −5j and −2j.To combine like terms, add their coefficients. The coefficients of −5j and −2j are −5 and −2, respectively.-5j + (-2j) = (-5 + (-2))j\(\newline= (-7)j= -7j\)
Write equivalent expression: Write down the equivalent expression after combining like terms.The constant term 3 remains unchanged as it is not a like term with j.The equivalent expression is −7j+3.
