Answer 1

a) (6x³- 2x² - 10x): 2x =

2(3x³+x²-5x)x

2

3x⁴-x³-5x²

b) (-15x⁶ - 20x⁵): 5x³ =

5(-3x⁶-4x⁵)x³

5

-3x⁹-4x⁸

c) (6x⁵ - 27x⁴+15x³) : (-3x²) =

3x²(2x³-9x²+5x)

3x²

2x³-9x²+5x

d) (-10x⁶+30x⁴ - 5x³):(-5x³) =

5x³(-2x³+6x+1)

-5x³

-(-2x³+6x+1)

2x³-6x-1

e) (3x²+2x-3)+(-3x²+4x-3)=

3x²+2x-3-3x²+4x-3

3x²-3x²+2x+4x-3-3

6x-6

f) (5x).(3x³-4x²+5x)= 15x⁴-20x³+25x²

g) (2x-3).(x²-4)= 2x³-8x-3x²+12
