- Yo, girl! My younger sister is asking some math questions and I don't know what to answer because I've already forgot about that since it's our lesson 2 years ago!
- It's about Illustrating quadratic equation.
- Ok, let me explain that inside of my house. Come in!
- Oh well, I think I can help you with that since I remember some of it, what's their topic all about?
- Ah yes! The quadratic term for that is ax^2, bx is the linear form, while, c is the constant form.
- Exactly! Examples:6x² + 11x - 35 = 02x² - 4x - 2 = 0-4x² -7x +12 = 020x² -15x - 10 = 0
- Their topic is Illustrating quadratic equation, right? Here let me explain in to you.
- A quadratic equation in one variable is a mathematical sentence of degree 2 that can be written in the following standard form ax² + bx + c, where a, b, and c are real numbers and a ≠ 0
- The easiest way to learn quadratic equations is to start in standard form. While not every quadratic equation you see will be in this form, it's still helpful to see examples. Keep in mind that the first constant a cannot be a zero.
- Next, apply the square root property if x²=n, then x=±√12.
- Solve for X and then check.
- Now to solve quadratic equation you need first to transform the quadratic equation in the form
- Remember if k0, then x²=k has two real solutions or roots.
- If k0, then x²=k has no real solutions or roots
- If k=0, then x²=k has one real solutions or roots.
- Omygosh, thank you so much! Now I know what to answer to my sister's question.
- No problem!
- Bye! Thank you again, I learn so much from you!!
- No problem! See youuuuu!!
