URGENT PLZ HELP!!!!!!!!
In this expression, Marianne claims that 2x and –x are not like terms because –x does not have a coefficient. Is she correct? Explain your reasoning. m squared + 2 x minus x + 3 m squared + 2

Answer 1

Answer:g

Marianne is incorrect because like terms are terms that have the same variables, raised to the same powers. The terms –x and 2x fit the definition for like terms. The term –x has a coefficient of –1. No, Marianne is not correct...

Hope it helps...

Answer 2

No, Marianne is incorrect.

In the given equation $m^2 + 2x - x + 3m^2+2$

Marianne claims that 2x and -x are not like terms because -x does not have a coefficient.

But this is incorrect because -x has a coefficient which is -1. If we state correctly we can see that the variable x has two coefficients 2 and -1. In the second term, 1 is not mentioned because 1 as a coefficient is generally not mentioned.

The given equation can be simplified and rewritten as: $4m^2 + x +2$
