chịu mk mới

học lớp 6 thui

chuc bn hoc gioi!

nhae@

hihison hihi

ê đừng có phá đám. ko biết thì thôi đừng có câu k

\(2x^3-12x^2+17x-2\)

\(=2x^3-4x^2-8x^2+16x+x-2\)

\(=2x^2\left(x-2\right)-8x\left(x-2\right)+\left(x-2\right)\)

\(=\left(2x^2-8x+1\right)\left(x-2\right)\)

\(2x^3-12x^2+17x-2\)

\(=2x^3-8x^2-4x^2+x+16x-2\)

\(=\left(2x^3-8x^2+x\right)-\left(4x^2-16x+2\right)\)

\(=x\left(2x^2-8x+1\right)-2\left(2x^2-8x+1\right)\)

\(=\left(2x^2-8x+1\right)\left(x-2\right)\)

2x³-12x²+17x-2

=2x³ - 4x² - 8x² + 16x +x-2

=2x².(x-2 ) - 8x.(x-2) +(x-2)

=(x-2)(2x² -8x +1)

2x³ - 12x² + 17x -2

=2x³-8x²-4x²+x+16x-2

=(2x³-8x²+x)-(4x²-16x-2)

=x(2x²-8x+1)-2(2x²-8x+1)

=(x-2)(2x²-8x+1)

help me

 2x^3−12x^2+17x−2

=(x−2)(2x2−8x+1)

~ ghi lời giải thôi ~

Cảm ơn ban nha

thanks

k tui nha đức

\(2x^3-12x^2+17x-2\)

\(=2x^3-4x^2-8x^2+16x+x-2\)

\(=2x^2\left(x-2\right)-8x\left(x-2\right)+\left(x-2\right)\)

\(=\left(x-2\right)\left(2x^2-8x+1\right)\)

2x³-12x²+17x-2=2x³-4x²-8x²+16x+x-2

=2x²(x-2)-8x(x-2) +(x-2)

=(x-2)(2x²-8x+1)

Chúc bn học giỏi

huhu , ai rảnh thì làm giúp mk vs ạ !!!

a)  \(x^3+8x^2+17x+10\)

\(=x^2\left(x+1\right)+7x\left(x+1\right)+10\left(x+1\right)\)

\(=\left(x+1\right)\left(x^2+7x+10\right)\)

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

b)  \(=x^4-2x^3-12x^2+12x+36\)

\(=x^2\left(x^2-2x-6\right)-2\left(x^2-2x-6\right)\)

\(=\left(x^2-2\right)\left(x^2-2x-6\right)\)
