The solutions of a quadratic equation are 5 and -1. What is the factored form of a related quadratic function? a f(x) = (x - 5)(x + 1) b f(x) = (x + 5)(x - 1) c f(x) = (x + 5)(x + 1) d f(x) = (x - 5)(x - 5)

Which is a logical conclusion based on the given information? a. figure abcd is a rhombus by the definition of a rhombus. b. segment ac is congruent to segment dc by cpctc. c. angle acb is congruent to angle adc by the angle-side-angle theorem. d. triangle acd is congruent to triangle cab by the hypotenuse-leg theorem.
