    Answer:

     \rm Numbers = 4 \ and \ -3.

    Step-by-step explanation:

    Given :-

    The sum of two numbers is 1 .

    The product of the nos . is 12 .

    And we need to find out the numbers. So let us take ,

    First number be x

    Second number be 1-x .

    According to first condition :-

    \rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}

    Hence the numbers are 4 and -3
