1. The importance of multiple-choice math questions
Multiple-choice questions are one of the important types of questions in mathematics exams, which can test students’ mastery of basic knowledge and their ability to flexibly use knowledge to solve problems. Below we will list 11 selected math multiple-choice questions, including geometry, algebra, probability and other knowledge points, with detailed answer analysis.
2. Detailed explanation and analysis of multiple-choice math questions
1. Question: What is the length of the side of a square with an area of 9 square centimeters?
Answer: Since the area of the square is equal to the square of the side length, the side length is the root number 9, which is 3 cm.
Analysis: This question examines the area formula of a square. The edge length is calculated by the formula.
2. Problem: If we know that the two roots of the unary quadratic equation ax²+bx+c=0 are x₁ and x₂, then the discriminant formula Δ=_______.
Answer: Discriminant Δ = b²-4ac. If Δ>0, the equation has two unequal real roots; If Δ=0, the equation has two equal real roots; If Δ<0, the equation has no real roots. Analysis: This question examines the discriminant formulas of one-dimensional quadratic equations and their applications. Solve according to the definition of the discriminant formula. 3.
