y" = -24 / y³
Step-by-step explanation:
6x² + y² = 4
Take the derivative of both sides with respect to x.
12x + 2y y' = 0
Again, take the derivative of both sides with respect to x.
12 + 2y y" + y' (2y') = 0
12 + 2y y" + 2(y')² = 0
Solve for y' in the first equation.
2y y' = -12x
y' = -6x/y
Substitute and solve for y":
12 + 2y y" + 2(-6x/y)² = 0
12 + 2y y" + 2(36x²/y²) = 0
12 + 2y y" + 72x²/y² = 0
6y² + y³ y" + 36x² = 0
y³ y" = -36x² − 6y²
y" = (-36x² − 6y²) / y³
Solve for y² in the original equation and substitute:
y² = 4 − 6x²
y" = (-36x² − 6(4 − 6x²)) / y³
y" = (-36x² − 24 + 36x²) / y³
y" = -24 / y³

B. For example:
is a polynomial
Step-by-step explanation:
A.
Degree is the highest power of the exponent in the polynomial.
A third degree polynomial is of form
. Its degree is 3.
This polynomial is in standard form as the terms are ordered from the biggest (3) to the lowest exponent (0).
B.
A polynomial is an expression consisting of variables and coefficients combined together using arithmetic operations. Exponents of variables are non-negative integers.
Polynomials are closed under addition as sum of two polynomial is also a polynomial.
For example: take two polynomials as![x+2,2x^2+4x+9](/tpl/images/0661/0046/3dabe.png)
