Question

Whats the discriminant of 2x²-36=x

Answer 1

Step-by-step explanation:

Given equation is 2x²-36=x

It can be written as 2x²-36-x= 0

=>2x²-x-36= 0

On comparing with the standard equation ax²+bx+c=0,

then we have,

a= 2, b = -1 ,c =-36

the discriminant (d) =b²-4ac

=>d= (-1)²-4(2)(-36)

=>d = 1-(-288)

=>d = 1+288

=>d = 289

The discriminant of the given equation is 289

The discriminant of the equation tells the nature of the roots.

if d>0 ,then the roots are real and distinct.

if d<0 then the roots are imaginary .

if d=0 then the roots are real and equal.
