What are the value of a and b respectively, if (3+3√5)/(3+√5) - (7-3√5)/(3-√5) = a+√5b ?

Here, we have to find the value of a and b.

➢ Multiplying the conjugate of their denominator to both the fractions.

So,

We know,

Then,

Combine both the fractions,

Therefore, we notice that

The value of a is 0 The value of b is 1

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.

All you have to do is multiply
