Q. Simplify. Write your answer using whole numbers and variables.7j−107j2−10j
Identify like terms: Identify like terms and simplify the expression if possible.The expression given is 7j2−7j10j−10. We first look for like terms to combine. In this case, there are no like terms to combine in the numerator or the denominator.
Simplify fraction: Simplify the fraction within the expression.We have a term with j in both the numerator and the denominator (7j10j). We can simplify this by dividing both the numerator and the denominator by j.7j10j=710
Substitute simplified fraction: Substitute the simplified fraction back into the expression.The expression now becomes 7j2−(710)−10. Since there is no j term in the fraction 710, we cannot combine it with the j2 term.
Combine constant terms: Combine the constant terms.We have two constant terms, −710 and −10, which we can combine by finding a common denominator.−710−10=−710−770=−780
Write final expression: Write the final simplified expression.The final expression, with the constant terms combined, is 7j2−780.
