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:
%28x-4%29%28x%2B3%29=0,expending the left side of the equation, we have:
x%5E2-x-12=0
Done.
