Q1 of 242 Page 9

If the equation x² + 4x + k = 0 has real and distinct roots, then

If roots of given equation are real and distinct then D = b² – 4ac > 0

Here a = 1, b = 4 and c = k

So, 4² – 4 (1) (k) >0

16 – 4k > 0

16 > 4k

K< 4

Find the discriminant of the quadratic equation 3√3x² + 10x + √3 = 0

If , is a solution of the quadratic equation 3x² + 2kx – 3 = 0, find the value of k.

If the equation x² – ax + 1 = 0 has two distinct roots, then
