Find the Value of k for Which the Roots Are Real and Equal in 3x² − 5x + 2k = 0

Find the Value of k for Which the Roots Are Real and Equal

Solution

Given: $$3x^2-5x+2k=0$$

Here, $$a=3,\quad b=-5,\quad c=2k$$

For real and equal roots, $$D=b^2-4ac=0$$

$$(-5)^2-4(3)(2k)=0$$

$$25-24k=0$$

$$k=\frac{25}{24}$$

Answer

The value of k for which the roots are real and equal is: $$\boxed{\frac{25}{24}}$$
