The product of two consecutive odd integers is 483.Find the integers.

Short Answer

Expert verified

The two consecutive odd integers are21,23and-23,-21.

Step by step solution

01

Step 1. Given Information

There are two consecutive odd integers whose product is483.

We have to find the integers.

02

Step 2. Finding the integers 

Let the first integer bex

and next consecutive odd integer bex+2

Therefore, the product of two consecutive odd integers is(x)(x+2)=483.

03

Step 3. Solve the equation

The equation we get is

(x)(x+2)=483x2+2x-483=0x2+23x-21x-483=0x(x+23)-21(x+23)=0(x-21)(x+23)=0

So,

x-21=0x=21and x+23=0x=-23

04

Step 4. Put the value of x in assumed integers to find the exact integers

If x=21

So, the first integer is21

And the next consecutive odd integer is

role="math" localid="1644589927253" 21+2=23.

If x=-23

So, the first integer is -23

And the next consecutive odd integer is

role="math" localid="1644590009758" -23+2=-21.

05

Step 5. Verify the integers 

As the product of two consecutive odd integers is483.

Let's verify the integers we get by multiplying them.

So, the two consecutive odd integers are 21,23and their product is21×23=483.

And another two consecutive odd integers are -23,-21and their product is(-23)×(-21)=483.

Thus, both pairs of consecutive odd integers are solutions.
