So writing a polynomial in standard form is just combining all like terms and then rearranging those terms in descending order of degree. In this case, the term with the highest degree is 2x^2, then 3x, then -6, so our standard form polynomial is
Next, since there are three terms in this polynomial,this would be classified as a trinomial (tri = 3). Now to find the degree of this polynomial, just take the total number of exponents from the highest term, which in this case its 2x^2 with a total of 2. Putting it all together, this polynomial is a 2nd degree trinomial.
The answer is y = 3x + 5 explanation : if you substitute the x in the equation for 0 and the y for 5 then solve/simplify. if you’re still not sure you can try the next one and substitute x for 2 and y for 11. you’ll see that y and x will equal each other. hope this helps:)
