Answer 1

X-2.........6x²+2x
______ . ________
4x²........x²+x-6

Δ=b²-4ac
Δ=1-4*(-6)
Δ=1+24
Δ=25

x₁=(-b-√Δ):2
x₁=(-1-5):2
x₁=-3

x₁=(-b+√Δ):2
x₁=(-1+5):2
x₁=2

x-2.........6x²+2x
______ . ________
4x²........(x+3)(x-2)

D=R-{0,-3,2}

x-2.........6x²+2x....x-2.....2x(3x+1).....(3x+1).....3x+1
______ . ________=_____.__________=________=______
4x²........(x+3)(x-2).. 4x²..(x+3)(x-2)....2x(x+3)....2x²+6x

x²-3x+2.......x-1
__________.-_____
(x-1)(2x+1)...2x+1

D=R-{1-½)

Δ=b²-4ac
Δ=(-3)²-4*2
Δ=9-8
Δ=1
x₁=(-b-√Δ):2
x₁=(3-1):2
x₁=-1
x₁=(-b+√Δ):2
x₁=(3+1):2
x₁=2

x²-3x+2.......x-1.....(2x+1)(x²-3x+2)...(x-1)(2x+1)(x-1)
__________.-_____=_________________-_________________=
(x-1)(2x+1)...2x+1...(x-1)(2x+1)(2x+1)...(x-1)(2x+1)(2x+1)


...2x³-6x²+4x+x²-3x+2...(2x²+x-2x-1)(x-1)
=___________________-________________=
(2x²+x-2x-1)(2x+1)......(2x²+x-2x-1)(2x+1)


2x³-5x²+x+2...................2x³+x²-2x²-x-2x²-x+2x+1
=_______________________-_______________________=
4x³+2x²-4x²-2x+2x²+x-2x-1..4x³+2x²-4x²-2x+2x²+x-2x-1


2x³-5x²+x+2....2x³-3x²+1.. -8x²+x+1
=____________-_________=___________
4x³-3x-1........4x³-3x-1........4x³-3x-1
