Question

The value of k which will make 8x²+8kx+3k+2

Answer 1

Answer:Given quadratic equation 4x² - 3kx + 1 = 0 has equal roots.

Here a = 4, b = -3k and c = 1.

Quadratic equation has equal roots then b2 - 4ac = 0

⇒ 9k2 - 16 = 0

⇒ k2 = 16 / 9

∴ k = ± 4/3.

Step-by-step explanation:

Given that equation has real and equal roots so, D=0

Compare the equation with ax2+bx+c=0

Now put the formula of D i.e, b2-4ac=0

Further putting the values we will get the answer
