The image contains several algebraic expressions, specifically quadratic equations and polynomial equations, along with steps to solve or manipulate them. The notation appears to be in a mix of English and another language (possibly Bengali), but the mathematical operations are clear.

Here is a breakdown of the steps shown:

1. Equation 1: $x^2 - 4x + 5$

   • The expression is given, and the next steps seem to involve solving it or further manipulating it.

2. Equation 2: $x - 4 + 10 = 0$

   • This is another equation, though it looks simpler and linear.

3. Equation 3: $4(x^2 - 4x + 5) + 10 = 0$

   • This equation is formed by multiplying the first equation by 4 and adding 10.

4. Equation 4: $x - 4(x^2 - 17x + 10) = 0$

   • This equation seems to be a modified version of the previous expressions, likely derived from some operation like distribution or factoring.

5. Equation 5: $4x^2 - 17x + 10 = 0$

   • A quadratic equation, possibly simplified from the previous expressions, ready for solving using the quadratic formula or factoring.

The process appears to involve forming and solving quadratic equations, applying operations like expansion, distribution, and simplification.
