Read this passage about seals and sea lions and then answer the question that follows: From a distance, they both look like seals, but once you get up close you can actually see the difference. Seals and sea lions are both fish-loving mammals. Moreover, handy flippers propel them both through the water. But while seals have a tiny opening on the side of their heads, sea lions have actual earflaps. Furthermore, sea lions use their back flippers like feet to scoot along the beach. On the other hand, seals must wriggle and roll to get ahead. On the whole, when you visit a zoo or theme park, it's the honking, barking, funny sea lion you're likely to find playing to the crowds for fishy treats, earflaps and all.

In the passage about seals and sea lions, which transition is used to show a contrast?

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
