Those are two very simple problems, and one interesting problem.

(1)
x and y.
x+y=13 and xy=40. Solve for x and y. You will use a quadratic equation.

(2)
x and y.
2x+2y=38 and xy=94. Solve for x and y. You will use a quadratic equation.

(3)
Very interesting.

Question asks for additive inverses of those roots to be roots in another equation, and to give that equation. "Form the equation...".
, this will serve.
