Quadratic, means you want or , for some number, 'a'. If -3 is the only and repeated solution, then this is only ONE root. Your equation is .

Naturally, a=1.

Write a quadratic equation having the given numbers as solutions.
-3,only solution(Hint:It must be a repeated solution.)
.
If -3 is a solution, then a factor MUST be:
(x+3)
if it is a "quadratic" it must be of degree 2
so (x+3) is repeated.
.
The quadratic equation is then
(x+3)(x+3)
we FOIL the above to get the equation:
x^2+3x+3x+9
x^2+6x+9
