e: \(E=\dfrac{x^2-9-x^2+4-x^2+9}{\left(x+3\right)\left(x-2\right)}\)
\(=\dfrac{x+2}{x+3}\)
a: \(A=\dfrac{4x^2+x^2-2x+1+x^2+2x+1}{\left(x-1\right)\left(x+1\right)}\)
\(=\dfrac{6x^2+2}{\left(x-1\right)\left(x+1\right)}\)
\(A=\dfrac{-4x^2+x^2-2x+1-x^2-2x-1}{\left(1-x\right)\left(1+x\right)}=\dfrac{-4x\left(x+1\right)}{\left(1-x\right)\left(1+x\right)}=\dfrac{4x}{x-1}\\ C=\dfrac{-x^2-4x-4+x^2-4x+4-4x^2}{\left(x-2\right)\left(x+2\right)}=\dfrac{-4x\left(x+2\right)}{\left(x-2\right)\left(x+2\right)}=\dfrac{4x}{2-x}\\ E=\dfrac{x^2-9-x^2+4x-4-x^2+9}{\left(x-2\right)\left(x+3\right)}=\dfrac{-\left(x-2\right)^2}{\left(x-2\right)\left(x+3\right)}=\dfrac{2-x}{x+3}\)
Mik đang cần gấp giúp mik giải vs ạ! Mik cảm ơn ạ!

Giúp mik với ạ, mik đang cần gấp. Cảm ơn ạ
giúp mik vs ạ, mik đang cần gấp ạ, c.ơn mn ạ<3
a. f(\(\dfrac{-1}{2}\)) = \(4.\left(\dfrac{-1}{2}\right)^2+3.\left(\dfrac{-1}{2}\right)-2\)
= \(4.\dfrac{1}{4}-\left(\dfrac{-3}{2}\right)-\dfrac{4}{2}\)
= \(\dfrac{2}{2}+\dfrac{3}{2}-\dfrac{4}{2}\)
= \(\dfrac{1}{2}\)
giúp mik vs ạ mik đang cần gấp . mik cảm ơn
bạn tự vẽ hình giúp mik nha
a.ta có \(\Delta\)ABC nội tiếp (O) và AB là đường kính nên \(\Delta\)ABC vuông tại C
trong \(\Delta ABC\) vuông tại C có
AC=AB.cosBAC=10.cos30=8,7
BC=AB.sinCAB=10.sin30=5
ta có Bx là tiếp tuyến của (O) nên Bx vuông góc với AB tại B
trong \(\Delta\)ABE vuông tại B có
\(cosBAE=\dfrac{AB}{AE}\Rightarrow AE=\dfrac{AB}{cosBAE}=\dfrac{10}{cos30}=11,5\)
mà:CE=AE-AC=11,5-8,7=2,8
b.áp dụng pytago vào \(\Delta ABE\) vuông tại B có
\(BE=\sqrt{AE^2-AB^2}=\sqrt{11,5^2-10^2}=5,7\)
