What is true about the completly simplified difference of the polynomials

6x^6-x^3y^4-5xy^5 and 4x^5y+2x^3y^4+5xy^5

•the difference has 3 terms and a degree of 6

•the difference has 4 terms and a degree of 6

•the difference has 3 terms and a degree of 7

•the difference has 4 terms and a degree of 7

the difference has 4 terms and a degree is 6.

Step-by-step explanation

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
