x=3,4

### Explanation of Solution

Given information:

x27x+12=0

Formula used:

Splitting the middle term:- in this method, middle term is splitted in such a way that the product of its part is equal to the product of constant and first terms coefficient.

Calculation:

x27x+12=0

Splitting middle term in such a way that product of its part is equal to product of constant and coefficient of first term.

x27x+12=0x24x3x+12=0x(x4)3(x4)=0(x3)(x4)=0

x=3,4
