Question

find the discriminant x^2 = 4

Answer 1

first write it in the form of
\(ax^2+bx+c=0\)

find, a,b,c
then discriminant is just
\(\Large D =b^2-4ac\)

Answer 2

your equation in full form looks like this
\[1x^2+0x-4=0\]
\[a=1, b=0, c=-4\]

Answer 3

now plug and chug

Answer 4

we need not solve it, only find the discriminant...and no, thats still not ok....

Answer 5

laughing out loud

Answer 6

@chathuranga , be care ful! -2 is another answer too as (-2)^2 = 4 too
