This math topic focuses on determining whether quadratic equations have one or more real roots. Students practice using the discriminant, \( b^2 - 4ac \), from the standard quadratic equation \( ax^2 + bx + c = 0 \), to ascertain the nature of the roots (real or imaginary). Each question presents a different quadratic equation, such as \( y=1.5x^2+2x+0.67 \), and asks whether the equation has real roots, with answers provided in a simple 'Yes' or 'No' format. This skill is vital for understanding the properties and solutions of quadratic functions.
