Question

write the discriminat of the quadratic equation (x+5)^2 = 2(5x-3) ​

Answer 1

heya

it's is... x^2 + 10x + 25 = 10x - 6

{using (a+b)^2}

then,

the equation will be x^2 +31

now, (using discriminant formula)

i.e, b^2- 4ac

0^2-4*1*31

gives -124

so d is in negative and hence it has no real roots....

hope it helps you....
