" (ii) "(7)/(4)x^(3)+(3)/(5)x^(2)+(1)/(2)x+(9)/(2)" from "(7)/(2)-(x)/(3)-(x^(2))/(5)

Take away: (7)/(4)x^(3)+(3)/(5)x^(2)+(1)/(2)x+(9)/(2) om (7)/(2)-(x)/(3)-(x^(2))/(5)

Take away (9)/(2)+(x)/(2)+(3)/(5)x^(2)+(7)/(4)x^(3) from (7)/(2)-(x)/(3)-(x^(2))/(5)

Add the algebraic expressions: (7)/(2)x^(3)-(1)/(2)x^(2)+(5)/(3),(3)/(2)x^(3)+(7)/(4)x^(2)-x+(1)/(3),(3)/(2)x^(2)-(5)/(2)x-2

If the lengths of the three sides of a triangle in units are (7)/(3)x^(3)-(1)/(2)x^(2)+(5)/(3),(3)/(2)x^(3)+(7)/(4)x^(2)-x+(1)/(3) and (3)/(2)x^(2)-(5)/(2)x-2 then its perimeter is

Add: (3x^(2) - (1)/(5)x + (7)/(3)) + ((-1)/(4)x^(2) + (1)/(3)x - (1)/(6)) + (-2x^(2) - (1)/(2)x + 5)

(6x-7)/(2)+(9-2x)/(5)=12+(x)/(4)-(2)/(3)+(4x)/(3)
