Question

phân tích thành nhân tử: x^2+6x+5

Answer 1

\(x^2+6x+5=x\left(x+1\right)+5\left(x+1\right)=\left(x+1\right)\left(x+5\right)\)

Answer 2

x² + 6x + 5 = x² + x + 5x + 5 = x(x + 1) + 5(x + 1) = (x + 5)(x + 1)

Answer 3

x²+6x+5=x²+5x+x+5=x(x+1)+5(x+1)=(x+5)(x+1)

Answer 4

\(x^2+6x+5=\left(x+5\right)\left(x+1\right)\)
