No. While the sum of two qudratics cannot have a power greater than two, it could have a power of 2, 1 or 0.
x2 + 1 is one quadratic
(2-x)(2+x) is another quadratic.
Their sum is 1, a constant (power = 0).

Is the sum of two rational numbers is it rational or irrational?
Such a sum is always rational.
Is the sum of two linear functions also a linear function?
Yes.
What are consecutive integers with the sum of 116?
The sum of two consecutive integers will always be an odd number.
Can the sum of three polynomials again be a polynomial?
The sum of two polynomials is always a polynomial. Therefore, it follows that the sum of more than two polynomials is also a polynomial.
What two number have the product of 121 and the sum of 22?
11 and 11. In general, you can write an equation (or two equations), and solve with the quadratic formula, to solve this type of questions.
Are the sum of two periodic functions always periodic?
yes
Is the sum of two linear functions always a linear function?
Yes. You would have to multiply to change it.
Is the graph of two continuous function is always continue?
Well, it sounds like a plausible statement, and maybe it would be true . But we haveno idea what the graph of two functions is.Perhaps you could graph the sum of two functions, or the difference of two functions,or their product, or their quotient. We believe that if the original two functions areboth continuous, then their sum and difference would also be continuous, but theirproduct and their quotient might not necessarily be continuous. However, we stilldon't know what the "graph of two functions" is.
Always use the vertex and at least points to graph each quadratic equation?
You should always use the vertex and at least two points to graph each quadratic equation. A good choice for two points are the intercepts of the quadratic equation.
Is the sum of two odd numbers is always odd?
The sum of two odd numbers is always even.
Can sum of two vectors be numeric?
No, the sum of two vectors cannot be a scalar.
Is the sum of two consecutive numbers always divisible by 2?
No, the sum of two consecutive numbers is always an odd number, and is not divisible by two.
The sum of two integers is an integer?
Yes the sum of two integers will always be an integer.
Is the sum of two rational numbers is it rational or irrational?
Such a sum is always rational.
Is the sum of two linear functions also a linear function?
Yes.
Is the sum of integers always an integer?
Yes, by definition, the sum of two integers is always an integer. Likewise, the product and difference of two integers is always an integer.
How do you use a quadratic equation to find two real numbers whose sum is 5 and whose product is -14?
