Question

2. Give examples of quadratic equations with (a) two real solutions, (b) one real solution, and (c)
no real solution.
3. Sheryl says that the solutions of the quadratic equations w2 = 49 and w2 + 49 = 0 are the
same. Do you agree with Sheryl? Justify your answer.​

Answer 1

Answer:

Quadratic equations differ from linear equations in that a linear equation has only one solution, while a quadratic equation has at most two solutions. There are some special situations, however, in which a quadratic equation has either one solution or no solutions. We solve quadratic equations using factorisation.
