Solve 4/(x + 1) - 1/x = 1 over the real numbers.

Answers

$( 4)/(x + 1) - (1)/(x) = 1 \n \nx+1\neq 0 \ \ \ and \ \ \ x\neq 0 \n \nx\neq -1 \ \ \ and \ \ \ x\neq 0 \n \nD=R\setminus \left \{ -1,0 \right \}$

$( 4x- (x+1))/(x(x + 1)) = 1 \n \n( 4x- x-1 )/(x^2+ x)=1 \n \n( 3x -1 )/(x^2 + x) = 1 \n \n3x-1=x^2+x\n \n x^2+x-3x+1=0$

$x^2-2x+1=0 \n \n (x-1)^2=0 \n \nx-1=0 \n \nx=1$

Find the product. a 4(3a 2 - 2a + 1)

Answers

Answer:

The product of $a^(4)(3a^(2)-2a+1)$ is $3a^(6)-2a^(5)+a^(4)$ .

Step-by-step explanation:

As given the expression in the question be as follow .

$= a^(4)(3a^(2)-2a+1)$

First open the bracket

$= a^(4)* 3a^(2)-a^(4)* 2a+a^(4)* 1$

Now by using the property of exponent .

$x^(a)* x^(b)= x^(a+b)$

$= 3a^(2+4)-2a^(4+1)+a^(4)$

$= 3a^(6)-2a^(5)+a^(4)$

Therefore the product of $a^(4)(3a^(2)-2a+1)$ is $3a^(6)-2a^(5)+a^(4)$ .

a^4(3a^2 - 2a + 1)

= 3a^6 - 2a^5 + a^4

What is multiplication?

The fundamental concept of making the same number of additions repeatedly is expressed by the action of multiplication. The results of multiplying two or more integers are known as the outcomes, and the factors that are used in the multiplication are referred to as the factors. The process of the complementing system of the same number is made simpler by multiplication.

From the given data in the question,

0.1 is times 10

0.1 × x = 10

x = 100.

If you multiply 0.1 by 10 you get 1. But then if you multiply 0.1 by 100, you get 10 because 100 has two zeros at the end and one is for moving the decimal point to the right which gives you 1 and the other one you add it at the end which is 10. Answer is 100 hope it helped.
