the rational number between √2 and √3
√2 = 1.414.
√3= 1.732.
So, a rational number between those two would be 1.5 (3/2). But there are several more, in fact, infinite number of rational numbers between √2 and √3.

Gaurav Seth 5 years, 7 months ago

For representing on a number line, we can opt for the following steps –

a.) Draw a number line of two points (units) from an initial point say. 0 in the right/positive direction

b.) Let those two points represent A & B respectively.

c.) Now, draw a line of 1-unit perpendicular to B and let it be called as C

d.) Join OC to represent the hypotenuse of a triangle, right angled at B

e.) This hypotenuse of triangle ABC is showing a length of

f.) We can use a divider and with the length of the hypotenuse, we can make a cut upon the number line.

Rahul Rohit 5 years, 7 months ago

Let p(x) be a polynomial of dagree 1or more and let a be any real number. If p(x) is divided by (x-a) then the remainder is p(a). In remainder theorem, p(x)= divudend g(x)= divisor q(x)= quotient r(x)= remainder

Yogita Ingle 5 years, 7 months ago

It is little tedious to divide 2 polynomials using the process described in previous section, So we use Remainder theorem.

Remainder theorem: Let p(x) be any polynomial of degree greater than or equal to one and let a be any real number. If p(x) is divided by the linear polynomial x – a, then the remainder is p(a).

Proof: Let p(x) be any polynomial with degree greater than or equal to 1. Suppose that when p(x) is divided by x – a, the quotient is q(x) and the remainder is r(x), i.e., p(x) = (x – a) q(x) + r(x) -- (i)

Since the degree of x – a is 1 and the degree of r(x) is less than the degree of x – a, the degree of r(x) = 0. This means that r(x) is a constant, say r. Thus we can re-write eq (i) as p(x) = (x – a) q(x) + r –(ii)

In particular, if x = a, then eq (ii) becomes p(a) = (a – a) q(a) + r = r,

Question: Find the remainder when p(x) = x⁴+ x³ – 2x² + x + 1 is divided by x – 1.

Solution: Zero of x – 1 is 1, so as per remainder theorem remainder in this case will be p(1) .

So, p(1) = (1)4 + (1)³ – 2(1)² + 1 + 1 = 2
