The solution of given quadratic equation is x = 4 and x = 5.

Step-by-step explanation:

We are given the following quadratic equation in the question:

x^2 - 9x + 20 =0

We have to solve the following quadratic equation by factorizing.

We use the technique of splitting the middle term.

$x^2 - 9x + 20 =0\\\Rightarrow x^2-5x-4x+20 = 0\\\Rightarrow x(x-5)-4(x-5) = 0\\\Rightarrow (x-4)(x-5) = 0\\\Rightarrow (x-4) =0, (x-5) = 0\\\Rightarrow x = 4, x = 5$

Thus, the solution of given quadratic equation is x = 4 and x = 5.
