💙Solving the power equation ✌️ using the formula

# Bank, butler, math tutoring # Math tutor # math # Math

4/8 Edited to

นอกจากการใช้สูตรกำลังสองหรือสูตรสำเร็จรูปที่บทความได้อธิบายไว้แล้ว ดิฉันพบว่าเมื่อเรียนกับติวเตอร์ที่มีประสบการณ์อย่างพี่แบงค์ จะช่วยให้เข้าใจที่มาของสูตรและการแทนค่าตัวแปรได้ชัดเจนขึ้นมาก วิธีที่สะดวกอีกอย่างคือลองเขียนสมการให้อยู่ในรูปมาตรฐาน ax² + bx + c = 0 เสมอ เพื่อให้สามารถใช้สูตรกำลังสองได้ทันที หากสมาชิกท่านใดพบว่าการคำนวณค่าภายใต้ราก (b²-4ac) ยาก สามารถขอคำอธิบายเพิ่มเติมจากติวเตอร์เพื่อเข้าใจแนวคิดการคำนวณส่วนนี้ได้ง่าย นอกจากนี้ เทคนิคที่ติวเตอร์ยิมมักแนะนำคือการตรวจสอบผลลัพธ์โดยการแทนค่า x ที่ได้กลับเข้าไปในสมการเดิมอย่างปลอดภัย เพื่อเช็คว่าคำตอบนั้นถูกต้องหรือไม่ วิธีนี้ช่วยป้องกันข้อผิดพลาดในงานสอบและการบ้านอย่างมาก สำหรับน้อง ๆ ที่สนใจการเรียนการสอนเพิ่มเติม แนะนำติดตามคลิปหรือหาคอร์สติวเตอร์ยิมเพื่อเสริมความรู้และการปฏิบัติที่มากขึ้น ทั้งนี้การเข้าใจสูตรอย่างแท้จริงจะช่วยให้การแก้สมการเป็นเรื่องง่ายและสนุกมากกว่าที่เคย

A person in workout attire stands next to text stating "CARBS DON'T MAKE YOU FAT!". Surrounding them are images of Fairlife chocolate milk, pasta with broccoli, bread, white rice, avocado, and ice cream, illustrating various food types.

A graphic titled "What Should I Eat? Foods with High Quality Carbs" displays images of butternut squash, granola, couscous, sweet potatoes, pasta, lentils, oats, cooked rice, and fruit, each with their carbohydrate content per serving.

Text outlines how to calculate carbohydrate needs for weight loss, including formulas for Basal Metabolic Rate (BMR) for men and women. A yellow cartoon character is shown thinking of a croissant.

Carbs are not the enemy!!✋🏼✨🩵 Weight loss With Carb

I wanted to talk about something that's been on my mind lately—carbohydrates. It seems like carbs have gotten a bad reputation, especially when it comes to weight loss. There's this belief out there that if you want to shed pounds, you have to avoid carbs at all costs. But let me tell y

A handwritten mathematical derivation on lined paper, showing the steps to find Pythagorean triples. It starts with a right-angled triangle labeled with sides a, b, and hypotenuse c, then derives the formulas a = m² - n², b = 2mn, and c = m² + n² from the Pythagorean theorem, with an example calculation for m=2, n=1 resulting in 3, 4, 5.

Deriving the formula to find Pythagorean triples

Given natural number m, n such that m > n > 0, then the derived formulae can be used to find Pythagorean triples. Pythagorean triples are sets of three whole numbers that satisfy the Pythagorean theorem. #math #maths #mathematics #geometry #trigonometry
