Explain the mathematical motivation for expanding to the rational number set.

Mathematics
1 answer:
NARA [144]3 years ago
3 0

Answer:

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. The set of all rational numbers, often referred to as "the rationals", the field of ... The decimal expansion of a rational number either terminates after a finite

What does b do in y=ax^2+bx+c. How can b being positive or negative affect a graph?
Dmitry_Shevchenko [17]

Answer:

The positions of the vertex and the axis of symmetry change.

Step-by-step explanation:

Let’s examine three parabolas in which a and c remain constant and only b changes.

(1) y = x² -  2x + 1

(2) y = x²         + 1

(3) y = x² + 2x + 1

In the image below,

Equation (1) is the black parabola, Equation (2) is green, and Equation (3) is red.

When b is more negative, the vertex moves down, and the axis of symmetry moves to the right.

When b is more positive, the vertex moves down, and the axis of symmetry moves to the left.

Hiiiiii peoples<br><br> Solve the inequality 6x^2-x&lt;2 please show all steps
Orlov [11]

Answer:(3x−2)⋅(2x+1)

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2"   was replaced by   "x^2".  

STEP

1

:

Equation at the end of step 1

 ((2•3x2) -  x) -  2

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  6x2-x-2  

The first term is,  6x2  its coefficient is  6 .

The middle term is,  -x  its coefficient is  -1 .

The last term, "the constant", is  -2  

Step-1 : Multiply the coefficient of the first term by the constant   6 • -2 = -12  

Step-2 : Find two factors of  -12  whose sum equals the coefficient of the middle term, which is   -1 .

     -12    +    1    =    -11  

     -6    +    2    =    -4  

     -4    +    3    =    -1    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  3  

                    6x2 - 4x + 3x - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

                   2x • (3x-2)

             Add up the last 2 terms, pulling out common factors :

                    1 • (3x-2)

Step-5 : Add up the four terms of step 4 :

                   (2x+1)  •  (3x-2)

            Which is the desired factorization

Final result :

 (3x - 2) • (2x + 1)
