hello, i want to ask about the example in 4:27 how do you cauculate (x^2+3x-10) using the cauculater as a quradratic equation? thanks a ton 🙏🙏🙏

5:25 DSE真的只會 - 3 to 3 嗎? 我學校教 check (+- 頭/尾)
其實點用二次公式做因式分解?thx
我喺 IDENTITY 度答咗堆嘢,你睇下仲有冇唔明project-identity.hk/3-factor-theorem-%E5%9B%A0%E5%BC%8F%E5%AE%9A%E7%90%86/
例子2 唔應該試x=-2,0,2
如果 ax+b is a factor of f(x), f(x)/ax+b 係唔係唔會有remainder.
係呀,呢個係 factor (因式) 嘅定義嚟嘛,你用數字諗就好易明:2 係 10 嘅 factor,所以 10/2 (等於 5) 就唔會有餘數喇。
