Answer:

I think the answer is 48

Step-by-step explanation:

cuz it's 12:3

and if you multiply 3 by 4 it'll be 12

so you multiply 12 by 4 as well, which is 48

mihht be wrong though

Use long division to find the quotient below (30x^3+4x^2-150) / (6x-10)

Anni [7]

Answer:

The answer is

A $.5x^2+9x+15$

Step-by-step explanation:

kindly find attached the solving for proper understanding and solution flow.

Given Data

the divisor= $6x-10$

dividend= $30x^3+4x^2-150$

firstly for us to perform the division we need to re write the dividend and include the missing coefficient of x

dividend $=30x^3+4x^2+0x-150$

Explain how you know which method you should use to solve a rational equation.

<u>Methods to solve rational equation:</u>

Rational equation:

A rational equation is an equation containing at least one rational expression.

Method 1:

The method for solving rational equations is to rewrite the rational expressions in terms of a common denominator. Then, since we know the numerators are equal, we can solve for the variable.

For example,

$\frac{1}{2}=\frac{x}{2}\Rightarrow x=1$

This can be used for rational equations with polynomials too.

For example,

$\frac{1+x}{x-3}=\frac{4}{x-3}\Rightarrow(1+x)=4 \Rightarrow x=3$

When the terms in a rational equation have unlike denominators, solving the equation will be as follows

$\frac{x+2}{8}=\frac{3}{4}$

$\Rightarrow\frac{x+2}{1}=\frac{3\times8}{4}\Rightarrow{x+2}=2\times3$

$\Rightarrow{x+2}=6\Rightarrow x=6-2\Rightarrow x=4$

Method 2:

Another way of solving the above equation is by finding least common denominator (LCD)

$\frac{x+2}{8}=\frac{3}{4}$

Factors of 4: $1\times2\times2$

Factors of 8: $1\times2\times2\times2$

The LCD of 4 and 8 is 8. So, we have to make the right hand side denominator as 8. This is done by the following step,

$\Rightarrow\frac{x+2}{8}=\frac{3}{4}\times{2}{2}$

we get,

$\Rightarrow\frac{x+2}{8}=\frac{6}{8}$

On cancelling 8 on both sides we get,

$\Rightarrow(x+2)=6\rightarrow x=6-2\rightarrow x=4$

Hence, these are the ways to solve a rational equation.
