Câu này em đã hỏi rồi
1.Tìm GTNN của Bthức : B= 4x2- 6x+1 : (x-2)2 với x ≠ 22. Tìm GTLN của Bthức: C= x2 + 4x - 14 : x2 -2x +1 với x≠ 1gi... - Hoc24
A=(-x2+x-11)/(x2-2*x+1)
tìm gtln,gtnn của biểu thức giúp e với ạ
1.Tìm GTLN của các biểu thức:
a,A= -x - 4y2 + 6x - 8y + 3
b, B= x4 - 6x3 + 15x2 - 20x - 15
2.Cho các số thực a,b thỏa mãn: 2a2 + \(\dfrac{b^2}{4}\)+\(\dfrac{1}{a^2}\)=4. Tìm GTNN và GTLN của A= ab+2019
giúp mình với ạ, mình cảm ơn
1. Tìm GTLN của biểu thức: B = 4x - x2 +3
2. Tìm GTNN của biểu thức \(Q=\frac{2x^2+2}{\left(x+1\right)^2}\)
Giúp mình với! Mình cần nó để soạn đề cương!
giúp mình với
cho biểu thức A=\(\frac{x^2-2x+2011}{x^2}\)với x>0.Tìm giá trị của x để A đạt giá trị nhỏ nhất.Tìm giá trị nhỏ nhất đó
mình đg cần gấp ạ!!
Bài 1 ( Cho đa thức A = 4n3 – 2n2 – 6n + 5 và đa thức B = 2n – 1.
Tìm giá trị nguyên của n để đa thức A chia hết cho đa thức B.
Bài 2
Tìm GTLN hoặc GTNN của biểu thức : Q = - x2 – y2 – 4x + 2y + 2
Các bạn giúp mik dc ko mik dag cần gấp ạ
Tìm GTNN của biểu thức:
a)A=x(x+3)(x-1)(x-4)
b)B=B=4x^4+4x^3+5x^2+4x+3
Mình đang cần gấp giúp mình với ạ
Tìm giá trị nhỏ nhất của biểu thức A=x^2+10x+35, m.n giúp với ạ, mình cần gấp lắm
Tìm giá trị nhỏ nhất của biểu thức : A= ( 3x^2 + 8x + 6 ) /( x^2 +2x + 1 )
Giúp mình với ạ. Mình đang cần gấp
Cho a,b,c ≥ 0 và a+b+c ≤ 3
Tìm GTNN của biểu thức B =\(\frac{1}{1+a}+\frac{1}{1+b}+\frac{1}{1+c}\)
LÀM ƠN MÌNH ĐANG CẦN GẤP Ạ AI GIÚP MK VỚI
