Question

for root 2 x square - 5 x + root 2 is equal to zero then the value of the discriminant is digest

Answer 1

Discriminant =

${b}^{2} - 4ac$

equation =

${2}^{2} - 5x + \sqrt{2}$

$- 5 ^{2} - 4 \times 2 \times \sqrt{2}$

$25 - 8 \times \sqrt{2}$

$25 - 8 \times 2 \times 2$

multiply "2" on both sides

$25 \times 2 - 8 \times 2$

$50 - 16$

$34 > 0$

therefore it has distinct roots
