    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.

    p(x) = 2x+7

    = 2x = -7

    x = -7/2

    zero of the polynomial = -7/2

    p( -7/2) = 2 ( -7/2 ) +7

    = -7+7=0
