The main formula for a polynomial ax^my^n+...
the degree is the sum of the highest degree of the polynomial, it is m+n
<span>the degree of x^3y^2+7x^2y^5-3xy^8 is 9, because </span><span>3xy^8 is the term where we can find a highest value of power (8)
so the degree is degree of x, it is 1 + degree of y (it is 8)
</span>
<span>Simplifying
2n + -7 + 3(4n + -3) = 0
Reorder the terms:
2n + -7 + 3(-3 + 4n) = 0
2n + -7 + (-3 * 3 + 4n * 3) = 0
2n + -7 + (-9 + 12n) = 0
Reorder the terms:
-7 + -9 + 2n + 12n = 0
Combine like terms: -7 + -9 = -16
-16 + 2n + 12n = 0
Combine like terms: 2n + 12n = 14n
-16 + 14n = 0
Solving
-16 + 14n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '16' to each side of the equation.
-16 + 16 + 14n = 0 + 16
Combine like terms: -16 + 16 = 0
0 + 14n = 0 + 16
14n = 0 + 16
Combine like terms: 0 + 16 = 16
14n = 16
Divide each side by '14'.
n = 1.142857143
Simplifying
n = 1.142857143</span>
