Question

Guys plzz solve and show the questions answer plzzz

Answer 1

2x^2 + x - 4 = 0

On Comparing this equation with General equation, we get

a = 2

b = 1

c = - 4


Discriminent = b^2-4ac

= 1 - (4)(2)(-4)

= 1 + 32

= 33


First root = ( - b + sqrt D) / 2a

=( - 1 +sqrt 33) / 4

Second root = (- b - sqrt D) / 2a

= (-1 - sqrt 33) / 4
