I NEED HELP ASAP

Explain the error in the work and how you might prevent it.

ANSWER:
-14x and 12x² are not like terms, so they can’t be subtracted.To prevent this error, be sure to line up like terms.

Respuesta :

For this case we have the following polynomials:
 Dividend: [tex]6x ^ 3 - 14x + 1[/tex]
 Divider:[tex] 3x + 6[/tex]
 We observe that when dividing the polynomials, we have the following quotient:
 Quotient: [tex]2x ^ 2[/tex]
 When making the division we see that we must subtract the following polynomials:
 [tex](6x ^ 3 - 14x + 1) - (6x ^ 3 - 12x ^ 2) [/tex]
 The mistake is:
 [tex]-14x - 12x ^ 2 = -26x ^ 2 [/tex]
 Since the terms are not similar, we can not subtract them.
 The correct subtraction is:
 [tex](6x ^ 3 - 14x + 1) - (6x ^ 3 - 12x ^ 2) = - 12x ^ 2 - 14x + 1 [/tex]
 Answer:
 
Error in subtraction of terms not similar

Answer:

Yes, there is an error because -14x and 12x² are not like terms, so they can’t be subtracted. To prevent this error, be sure to line up like terms.

Step-by-step explanation:

We need to check whether the given work is error free or not.

In the given problem [tex]6x^3+1-14x[/tex] is divided by [tex]3x+6[/tex].

In this case,

[tex]Dividend=6x^3+0x^2-14x+1[/tex]

[tex]Divisor=3x+6[/tex]

Using long division we get

[tex]\frac{6x^3+1-14x}{3x+6}=2 x^2 - 4 x+ \frac{10}{3}-\frac{19}{3 (x + 2)}[/tex]

So,

[tex]Quotient=2 x^2 - 4 x + \frac{10}{3}[/tex]

[tex]Remainder =-19[/tex]

It the given work there is an error because -14x and 12x² are not like terms, so they can’t be subtracted. To prevent this error, be sure to line up like terms.
