Answer 2

Answer: $\frac{2}{100}$

Step-by-step explanation:

In the method of Completing the Square, we solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial.

If we have a quadratic equation,

x² + bx + c, then we can make it a perfect square trinomial by adding or subtracting b²/ 2 .

Here, the given function,

5x²- √2x+3=0

⇒ x² - √2/5 x = -3/5

For solving this equation, we need to make the left side a perfect square trinomial,

By the above rule, we need to add or subtract (√2/10)² on the left side of the equation,

Hence, the required coefficient is 2/100.
