Question 432020
Solution:Every quadratic equation can be written in the form:a(x-x1)(x-x2)=0,

where a is the coefficient beside x^2, and x1, x2 the roots.

To create an equation with x1=4 and x2=-3, we let a=1 and substitute:

{{{(x-4)(x+3)=0}}},expending the left side of the equation, we have:

{{{x^2-x-12=0}}}

Done.
