Question

Find the sum of the zeroes of p(x) = (x - 3) and q(x) = (2x - 8)?

• A. 3
• B. 4
• C. 7
• D. 8

Answer 1

The correct option is C 7

If k is a zero of the polynomial p(x), then p(k) = 0.

Here, we need to find the zeroes of p(x) and q(x). To find the zeroes we need to equate the polynomial to 0.

p(x) = x - 3 = 0
$\Rightarrow$ x = 3
$\Rightarrow$ x = 3 is the zero of the polynomial p(x).

Similarly, q(x) = 2x - 8 = 0
$\Rightarrow$ x = 4
$\Rightarrow$ x = 4 is the zero of the polynomial q(x).

$\therefore$ Sum of the zeroes of p(x) and q(x) is 7.
