Q. Simplify. Write your answer using whole numbers and variables.j−7j2−7j
Identify Expression: Identify the expression to be simplified. The expression given is (j2−7j)/(j−7). We need to simplify this expression by factoring if possible.
Factor Out Common Term: Factor out the common term in the numerator.The numerator j2−7j can be factored by taking out the common factor j. This gives us j(j−7).
Rewrite with Factored Numerator: Rewrite the expression with the factored numerator. The expression now becomes (j(j−7))/(j−7).
Cancel Common Terms: Cancel out the common terms in the numerator and the denominator.The term (j−7) is present in both the numerator and the denominator, so we can cancel it out, as long as j=7 (since division by zero is undefined).The expression simplifies to j.
