Answer 2

Step-by-step explanation:

The given polynomial is f(x) = 2x4 – 11x3 + 7x2 + 13x – 7. Since (3 + √2) and (3 – √2) are the zeroes of f(x) it follows that each one of (x + 3 + √2) and (x + 3 – √2) is a factor of f(x). Consequently, [(x – ( 3 + √2)] [(x – (3 – √2)] = [(x – 3) - √2 ] [(x – 3) + √2 ] = [(x – 3)2 – 2 ] = x2 – 6x + 7, which is a factor of f(x). On dividing f(x) by (x2 – 6x + 7), we get: Read more on Sarthaks.com - https://www.sarthaks.com/129458/find-all-the-zeroes-of-polynomial-2x-11x-7x-13x-it-being-given-that-two-of-its-zeroes-are-2-and
