Question

Calculati:
a) (9x^3y^2-6x^2y+12x^2y^2) : 3x^2y + 2(x+2y) =
b) (42x^5+14x^4-7x^2+7x^2) : 7x^2 - (25x^5-15x^4+10x^3) : 5x^3 =
c) (2x^3+3v3x^2+x) : x + (4v3x^2-6v3x+7v3) : v3 + x^2 =

Answer 1

a. 3x y2 -2x+4x 2 +2x+4y
3x 2y -2x+8y+2x+4y
3x +14y
b. 7x 2.5+2x2 - x -(5x1.2 -3x1.1 +2x)
7x ori 2.5 +4x-x-5x ori 1.2+3.3x-2x
c. 6 +18 +1 + x - x+7
35+7
