Question

If a polynomial p(x) is given by p(x) = x² - 5x + 6, then the value of p(1) + p(4) is ______.

Options

• 0

• 4

• 2

• -4

Answer 1

If a polynomial p(x) is given by p(x) = x² - 5x + 6, then the value of p(1) + p(4) is 4.

Explanation:

p(1) = 1² - 5(1) + 6 = 1 - 5 + 6 = 2

p(4) = 4² - 5(4) + 6 = 16 - 20 + 6 = 2

p(1) + p(4) = 2 + 2 = 4
