Question

answer the following questions​

Answer 1

Answer:

2.  B)$\sqrt{3x^{2} } +2x-7$ is non-polynomial expression.

Step-by-step explanation:

2. Some non-polynomial equations can be solved using polynomial equations. As an example let us consider the equation √(15-2x) = x. First we note that this is not a polynomial equation. Squaring both sides, we get x2 + 2x −15 = 0 . We know how to solve this polynomial equation. From the solutions of the polynomial equation, we can analyse the given equation. Clearly 3 and −5 are solutions of x2 + 2x −15 = 0 . If we adopt the notion of assigning only non negative values for √ •  then x = 3 is the only solution; if we do not adopt the notion, then we get x = −5 is also a solution.

By the given question ,we can write  B)$\sqrt{3x^{2} } +2x-7$ is non-polynomial expression.
