Both claims are false. In fact,
and
are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that

So, it doesn't matter if
is positive or negative: the multiplication of one number and its inverse will always be 1: for example,

Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:
So, the multiplication of two negative numbers is a positive number.
(2,-1), (-4,17).
Step-by-step explanation:
Equate the equation A and equation B
Convert the quadratic equation in factored form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
Find the values of y
Substitute the value of x in the equation B
The answer to your question is b.
