CAC BAN TRA LOI NHANH HO TUI NHE
tim max va min cua D=\(\frac{3-4x}{x^2+1}\)
GIẢI NHANH NHÉ !!!
Tim Min va Max cua bieu thuc A=(3-4x):(x^2+1)
ban nao giai ho minh a . Tim MAX [ GTLN]
P = -2x2 - 5y2 + 2xy + 4x + 4y + 2010
a)tim GTLN cua P=x^2/x^4+x^2+1
b)cho 4x+5y=40, tinh GTLN cua Q=xy
1)Tim MAX cua A= (6x^2-2x+1)/ x^2
2)tim MIN va MAX C= (3-4x)/(X^2+1)
3) Tim MIN va MAX P = x^2+y^2
biet giua x va y co moi quan he nhu sau : 5x^2+8xy+5y^2=36
4)tim MAX Q = -x^2-y^2+xy+2x+2y
