\(A=x\left(3-4x\right)+\left(2x-1\right)\left(2x+1\right)=3x-4x^2+4x^2-1=3x-1\)
\(A=x\left(3-4x\right)+\left(2x-1\right)\left(2x+1\right)=3x-4x^2+4x^2-1=3x-1\)
Rút gon:
2x( 2x-1)^2 - 3x(x+3)(x-3) - 4x(x+1)^2
Rút gon: (2x+1)2+2x(4x2-1)+(2x-1)2
Rút gon biểu thức \(A=\frac{x^2+2x}{x^2-4x+4}:\left(\frac{x+2}{x}-\frac{1}{2-x}+\frac{6-x^2}{x^2-2x}\right)\)
giá trị rút gon cua bieu thuc
(2x-4)*(x+3)-2x(x+1)
rút gọn biểu thức
a)A= (2x - 3)^2 - (2x + 3)^2
b)B= (x +1)^2 -2 (2x-1) (1+ x) +4x^2 - 4x + 1
Rut gon a biet a=(x^2-2x/2^2+8+2x^2/8-4x+2x^2-x^3)x(1-1/-2/^2)
Ai giup minh minh tick nha ::)))
Rút gon biểu thức sau:
\(\left(x^2-2\right)^2-\left(2x^5-8x^3+4x\right):2x\)
rut gon bieu thuc a,(3x+2)^2+4x-3^2+2(5x-2)(5x+2)-75x^2
b,(x-2)^3+(2x+1)^3++2(x+2)(1-x)-9x^3+2x
thu gon
2x(2x-1)2-3x(x+3)(x-3)-4x(x+1)2
