\(\Delta\)ABC cân tại A, I thuộc BC gọi M,N là hình chiếu của I lên AB và AC vẽ đường cao BH, K là hình chiếu của I lên BH

a)cm BK=MI

b)CM IM+IN=BH\(\Rightarrow\)IM+IN ko đổi khi Idi chuyển trên BC

\(\Delta\)ABC nhọn vẽ ra phía ngoài các tam giac vuông cân. tam giác ABD vuông cân tại B tam giác ACE vuông cân tại C vẽ đường cao AH gọi I và K lần lượt là hình chiếu của D và E lên BC

a) CM BI=CK

b)HC=EK

c)BC=DI+EK

a)P=(x+2)2+x(x−4)P=(x+2)2+x(x−4) tìm nhỏ nhất của p

b)A=(2x−1)(x+2)−x(2x+5)A=(2x−1)(x+2)−x(2x+5) tìm x để A =0

c)P=(2−3x)(x−5)−2x(−x+8)+10P=(2−3x)(x−5)−2x(−x+8)+10 tìm nghiệm của p

d)A=(x+1)(x2−x+1)−x(x2−x)A=(x+1)(x2−x+1)−x(x2−x)tìm giá trị nhỏ nhất của A

tìm giá trị nhỏ nhất

a)\(A=|x-1|+|5-x|+3\)

b)\(B=4x^2-5\)

c) C=x²+2x+5
