Answer:
2.The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.
Step-by-step explanation:
A quadratic equation is any equation that can be rearranged in standard form as :
ax² + bx + c = 0
Where a, b and c are coefficients and a ≠ 0.
Since for a quadratic equation, the power of x is a non negative integer, it is considered as a polynomial. A quadratic equation is a second-degree polynomial (i.e the gratest power of x is two).
The equation is not a quadratic equation because it cannot be rewritten as a second-degree polynomial.
We want to see which statement describes the equation x^5 + x^3 - 14 = 0.
The correct option is:
The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.
First, our equation:
x^5 + x^3 - 14 = 0.
Is a polynomial of degree 5 (the degree is equal to the maximum exponent).
Thus, this is not a quadratic equation.
Where a quadratic equation is a polynomial of degree 2.
Notice that we also can't replace x by another variable, such that it becomes a quadratic equation, then the correct statement is:
The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.
