#-35x#

The seven is traditionally positive because we are not given a sign for it.

Write as #(-5)xx(+7)xx x#

If the signs differ when multiplying or dividing, the result is negative; if they are the same, the result is positive.

We are not given any sign for the #x# so by convention it is positive

#"Just the numbers"->(-5)xx(+7)=-35#

#"Combine with the "x->(-35)xx(+x)=-35x#

To simplify (-5x \times 7x), you multiply the coefficients (-5 and 7) and add the exponents of the variable (x). So, (-5x \times 7x) simplifies to (-35x^2).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
