Introduction

On this occasion, I made a post about a quiz on congruence and congruence material in the form of multiple choice questions. Previously, students had studied the material congruence and congruence

. This material is the first material taught in class 9 of SMP/MTS this even semester.

Introduction

On this occasion, I made a post about the odd mid-semester assessment quiz for class 9 SMP/MTs with multiple choice questions, where the question script had been previously created using LaTeX. One of the advantages of writing question papers in LaTeX is that the display of mathematical formulas or symbols is neat and in accordance with scientific rules for writing mathematical notation. To see a guide to making mid-semester assessment questions using LaTeX, you can read the post Creating Midterm Assessment Questions in LaTeX.

Introduction

On this occasion, we will share a quiz about the form of roots and powers of fractions. The material on roots and exponents of fractions is one of the materials taught in class IX middle school odd semester. You can view and study the material again here

Introduction

Power numbers are one of the materials studied in class IX odd semester. To learn it, please reopen the material rank number

. The basics of exponent number material have previously been studied in class VII in whole number material. To measure understanding regarding the material on exponents, please take the following quiz on exponents.

Introduction

Many daily-life problems can be solved using quadratic functions by first expressing them as mathematical models. Once the model is built, the problem can be solved systematically.

Example Problems

Problem 1

The sum of two integers is 20. Determine the greatest possible product of the two numbers.

Introduction

After studying quadratic equations, it is time to do an assessment to measure competency achievement. This quiz was originally prepared for students of SMPN Purworejo, Padang Ratu District, Central Lampung.

Other readers are also welcome to try the quiz or share it with their students.

Introduction

Quadratic equations can be solved in three main ways:

1. Factoring, which changes the sum of algebraic terms into a product form.
2. Completing the square, which changes the general form into a perfect-square form.
3. The quadratic formula or abc formula, which gives the roots directly.

This article focuses on solving quadratic equations by factoring and completing the square.

Introduction

To find the roots of a quadratic equation, we can use factoring, completing the square, or the quadratic formula often called the abc formula:

This article focuses on solving quadratic equations using that formula.
