Tick nha 😘
Đây nè bạn đã cố gắng ko làm tắt rồi nhé bạn
a: \(4x^2-6x=2x\left(2x-3\right)\)
b: \(9x^4y^3+3x^2y^4=3x^2y^3\left(3x^2+y\right)\)
c: \(x^3-2x^2+5x=x\left(x^2-2x+5\right)\)
d: \(3x\left(x-1\right)+5\left(x-1\right)=\left(x-1\right)\left(3x+5\right)\)
e: \(2x^2\left(x+1\right)+4\left(x+1\right)=2\left(x+1\right)\left(x^2+2\right)\)
f: \(2x^2y-4xy^2+6xy=2xy\left(x-2y+3\right)\)
