Question

find the discriminent of 2xsquare+10x+21=0

Answer 1

Heyaa☺
____________________

Given equation,

2x^2 + 10 x + 21 =0

Discriminent

=》 b^2 - 4ac / 2a

=》100 - 4(2)(21) / 2(2)

=》100 - 168 / 4

=》-68/4

▶-17//

⚫The discriminant of the given equation is less than O.Hence,the roots are real and imaginary.
