Phân tích đa thức thành nhân tử 
5x^2-5x-10

Answer 1

\(5x^2-5x-10=5x^2+5x-10x-10=5x\left(x+1\right)-10\left(x+1\right)=\left(5x-10\right)\left(x+1\right)\)

Answer 2

5x2−5x−10=5x2+5x−10x−10=5x(x+1)−10(x+1)=(5x−10)(x+1)

Answer 3

 \(5x^{2}-5x-10\)

\(=5x^{2}+5x-10x-10\)

\(=(5x-10)(x+1)\)

 

 

 

Answer 4

\(5x^2-5x-10=5\left(x^2-x-2\right)=5\left(x-2\right)\left(x+1\right)\)
