Question

Find 'k' for real roots :x²+kx+4=0​

Answer 1

Answer:

answer for the given problem is given

Step-by-step explanation:

Let ax^2+bx+c=0 be a quadratic equation then b^-4ac is called its discriminant and

it is denoted by d.

If the equation has equal and real roots then b^2-4ac =0

If the equation has real and distinct roots then b^2-4ac>0

If the equation has no real roots then b^2-4ac<0
