Question

Write a quadratic equation with the solutions x=-5+sqrt 13/2 , -5-sqrt 13 /2 HELP please

Answer 1

If we used the quadratic formula to solve the equation we can say:

-b = -5

b² - 4ac = 13

2a = 2

Solving the first and last equations we get b = 5 and a = 1. Substituting these values into the second equation we get:

25 - 4c = 13

Solving this we get c = 3 so the answer is x² + 5x + 3.
