Quadratic equation and type of solution(s)

Question

find a possible pair of integer values for a and c so that the quadratic equation has a given number and type of solution(s). Then write the equation.

14. ax² + 12x + c = 0; one real solution

15. ax² – 5x = c; two real solutions

16. 2x + c = ax²; two imaginary solutions

Answer 1

Set each equation equal to zero. (Like A)

One real zero: b² - 4ac = 0

Two real zdero: b² - 4ac > 0

Two complex zero: b² - 4ac < 0
