Answer 1

Answer:

In a field of characteristic other than 22, the usual quadratic formula

−b±b2−4ac−−−−−−−√2a−b±b2−4ac2a

provides the roots of the quadratic polynomial ax2+bx+cax2+bx+c. So the roots of x2−2=2(12x2−1)x2−2=2(12x2−1) are

−0±02−4×12(−1)−−−−−−−−−−−−√2×12=±2–√.−0±02−4×12(−1)2×12=±2.

Answer 2

Answer:

$7\sqrt{2} \times 2 - 10x - 4 \sqrt{2}$

$7 \sqrt{2} - 5x - 2 \sqrt{2}$
