Question

find the zeros of the quadratic polynomial and verify the relation between zeroes and coefficients 2root2xsquare -9x+5root2

Pls help me!!!
Its very urgent

Answer 1

Answer:

$2 \sqrt{2} {x}^{2} - 9x + 5 \sqrt{2} \\2 \sqrt{2} {x}^{2} - 5x - 4x + 5 \sqrt{2} \\ x(2 \sqrt{2} x - 5) - \sqrt{2} (2 \sqrt{2} x - 5) \\ (x - \sqrt{2} )(2 \sqrt{2} x - 5) \\ x - \sqrt{2} = 0 \\ = > \bold{ \underline{ x = \sqrt{2} }} \\ 2 \sqrt{2} x - 5 = 0 \\ = > 2 \sqrt{2}x = 5 \\ = > \bold{\underline{ x = \frac{5}{2 \sqrt{2} } }}$

hope it helps you.....
