Answer:

Hey mate. , here is your answer ❣️❣️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Step-by-step explanation:

Roots are that values of variables in the equation which satisfy the given equation .

We can find the roots by the process of factorization

Two main ways of factorization :-

1) Splitting middle term

2) Using Baudhayan formula

We are going to use method 1 here :-

Given equation :- x^2 - 7x + 12 = 0

→ x^2 - 4x - 3x + 12 = 0

→ x(x-4) - 3( x - 4 ) = 0

→ ( x - 3 ) ( x - 4 )= 0

→ ( x - 3 ) = 0. or , ( x - 4 ) = 0

→ x = 3 or , x = 4

Hence , the required roots of the given equation are 3 and 4 .............

Please mark it as brainliest answer :-)
