Question 1

What is the discriminant of the quadratic equation $2x^2 - 5x + 3 = 0$, and what is the nature of its roots?

Discriminant is 1; two distinct real roots Discriminant is -1; no real roots Discriminant is 49; two distinct real roots Discriminant is 0; two equal real roots

Correct Answer:

Discriminant is 1; two distinct real roots

Question 2

Express the quadratic expression $x^2 - 6x + 13$ in the completed square form $(x - p)^2 + q$. What are the values of $p$ and $q$?

$$p = 3$, $q = 22$ $$p = 3$, $q = 4$ $$p = -3$, $q = 4$ $$p = 6$, $q = 13$

Correct Answer:

$$p = 3$, $q = 4$

Question 3

Find the set of values of $x$ satisfying the quadratic inequality $x^2 - 4x - 5 \le 0$.

$$x \le -1$ or $x \ge 5$ $$x < -5$ or $x > 1$ $$-1 \le x \le 5$ $$-5 \le x \le 1$

Correct Answer:

$$-1 \le x \le 5$

Question 4

The quadratic equation $kx^2 + 6x + 1 = 0$ has two equal real roots. Determine the value of the non-zero constant $k$.

$$k = 1$ $$k = 3$ $$k = 6$ $$k = 9$

Correct Answer:

$$k = 9$
