Question

find the zeros of quadratic polynomial of 2x squre - 50

Answer 1

$a {}^{2} - b {}^{2} = (a + b)(a- b)$
$2x {}^{2} - 25 = (root 2x + 5( root 2 x- 5)$
finding x from (root 2x+ 5)
x= (- 5/root 2 )
finding x from (root 2x- 5)
x=( 5/root 2 )
therefore the zeroes are(- 5/root 2 ) and (5/root 2)
