Question

For the polynomial 6xy2−5x2y?+9x2 to be a trinomial with a degree of 3 after it has been fully simplified, what is the missing exponent of the y in the second term?

Answer 1

Answer:

The Answer is 1

Step-by-step explanation:

Answer 2

Answer:

B - 1

Step-by-step explanation:

If you have 6xy² - 5x²y¹ + 9x² you wouldn't need to simplify any further

This is the equation we get from adding ¹ as the missing exponent

This fits the description because it is a trinomial (has three terms) 6xy² is one term -5x²y¹ is the second and 9x² is the third

It is also to a degree of three because 3 is the highest sum of exponents within a term. 5x²y¹ has exponents 2 and 1 which adds up to three

I hope this helps :)
