The ordered pairs of $p(x) = x^{2}-2\cdot x -35$ are $(r_{1}, p(r_{1})) = (-5, 0)$ and $(r_{2},p(r_{2})) = (7,0)$ , respectively.

Step-by-step explanation:

Let be p(x) a quadratic expression whose two real zeros are real, a value of is a zero of the expression when p(x) = 0 . The factored form of the expression is represented by $p(x) = (x-r_{1})\cdot (x-r_{2})$ , where $r_{1}$ and $r_{2}$ are the zeroes of the polynomial.
