Question

The zero of the polynomial p(x) =2x+5

Answer 1

Answer: -5/2 is the required zero of the polynomial p(x) = 2x + 5.

Step-by-step explanation:

Given: A polynomial p(x) = 2x + 5

To find: The zero of p(x) = 2x + 5

Solution:

Let's find the zeroes of the polynomial:

⇒ p(x) = 0

⇒ 2x + 5 = 0

⇒ 2x = -5

⇒ x = -5/2

Know more:

1. We can observe that the given polynomial is known as linear polynomial.
2. Consider a linear polynomial p(x) = ax + b. Then, its zero is likely to be -b/a (or) [-(Constant)/Coefficient of x]
3. In a linear polynomial, we can only expect one zero and more than that is not possible.
4. If we plot the linear polynomial in graph, we get a straight line and the line meets at a particular point, which is the zero of the polynomial.
