Tara would like to finish 2/5 of her book by next Friday. If the book has 203, about how many pages does she need to read? PLZZZ

<u>Answer: </u>
f(x) = 3(x+2)(x-2)
<u>Step-by-step explanation: </u>
We are given the following the quadratic function and we are to rewrite it in intercept or factored form:
We can factorize the given function so taking the common factors out of it to get:
The term is in the form
so it can further be factorized to give:
Therefore, the factored form of the given quadratic function is f(x) = 3(x+2)(x-2).
6. When we multiply two surdic integers, we can leave it into one big surd.
For instance, if we have:
, we can simplify it down to one uniform square root sign, 
.
So, we can say:
, which is a rational root, because the square root of 36 can be converted into an integer, namely 6 and -6.
Hence, it is a rational root.
7. The summation, on the other hand, cannot be simplified any further, so it will stay as irrational. This is because √2 is already an irrational root, and adding it onto a number that is rational will stay as irrational.
8. Once again, the summation cannot be simplified. We can only simplify by factoring like terms. Hence, this must be irrational.
9. Even if it is in fractional notation, √5 can never be a rational number because no two integers when multiplied by itself will give 5. So, even if it is written in fractional form, they cannot be rational if there is an already irrational term in it.
