Answer:
p(x) = 2x + 7
Zero of the polynomial is a number which when substituted in the equation will make its value zero.
To find the zero of the polynomial, one should equate the equation by zero.
➸ 2x + 7 = 0
Then, it is solved.
➸ 2x = -7
➸ x = -7/2
Now, let is check whether the answer is correct.
➸ 2x + 7
➸ 2(-7/2) + 7
➸ - 7 + 7
➸ 0
Hence, -7/2 is the zero of the polynomial.
ADDITIONAL INFORMATION –
A linear equation has one zero.
A quadratic equation has two zeros.
A cubic equation has three zeros.
That is, the number of zeros increases as the degree of the polynomial increase.
The degree of the polynomial is said to be the highest power of a term in the equation.
