Answer 2

Answer:

The roots of the equation are 3 or 12.

Step-by-step explanation:

Given: $x^2 - 15x +36=0$

We have to solve the given data.

We are solving in the following way:

We have,

$x^2 - 15x +36=0$

We will split the middle term, such that the product of the numbers is the last term and the sum or difference of those numbers is the middle term.

Here, the middle term is -15x and the last term is 36.

$x^2 - 15x +36=0$

$=>x^2-3x-12x+36\\=>x(x-3)-12(x-3)$

$=>x-3=0\\=>x-12=0$

Then,

$=>x=3 \ or\ x=12$
