The error is in step 2. if you are performing an operation on one side of the equation, it must be performed on the entire expression. you can’t only divide by 2 on one term, you must do it to everything in the equation. instead, you could add 6 to both sides first, giving you 2x = -4. Then you can divide by 2 on both sides. the answer is -2.

I’m stuck... any one able to help?<br> X^4 + 5x^3 + 3x/x

Leni [432]

Answer:

$x^3+5x^2+3x$

Step-by-step explanation:

1) divide each term in the numerator by the term in denominator:

(remember when dividing subtract the smaller exponent from larger exponent

for example: $\frac{x^a}{x^b}$ say a is the larger exponent, do $x^a^-^b$

x^4/x=x^3

5x^3/x=5x^2

3x^2/x=3x

so

x^3+5x^2+3x

hope this helps!
