Phương trình bậc hai có dạng: a\(x^2\) + b\(x\) + c
Bước 1: Đưa nó về bình phương của một tổng hoặc một hiệu cộng với một số nào đó. nếu a > 0 thì em sẽ tìm giá trị nhỏ nhất; nếu a < 0 thì em sẽ tìm giá trị lớn nhất
Bước 2: lập luận chỉ ra giá trị lớn nhất hoặc nhỏ nhất
Bước 3: kết luận
Giải:
A = 3\(x^2\) - 5\(x\) + 3 Vì a = 3 > 0 vậy biểu thức A chỉ tồn tại giá trị nhỏ nhất
A = 3\(x^2\) - 5\(x\) + 3
A = 3.(\(x\)2 - 2.\(x\).\(\dfrac{5}{6}\) + \(\dfrac{25}{36}\)) + \(\dfrac{11}{12}\)
A = 3.(\(x\) - \(\dfrac{5}{6}\))2 + \(\dfrac{11}{12}\)
Vì (\(x-\dfrac{5}{6}\))2 ≥ 0 ⇒ 3.(\(x\) - \(\dfrac{5}{6}\))2 ≥ 0 ⇒ 3.(\(x-\dfrac{5}{6}\))2 + \(\dfrac{11}{12}\) ≥ \(\dfrac{11}{12}\)
Amin = \(\dfrac{11}{12}\) ⇔ \(x\) = \(\dfrac{5}{6}\)
