Show all steps please!(X^3+2x-1) - (2x^2+4x-2)
(x^3+2x-1)-(2x^2+4x-2) = x^3 + 2x - 1 - 2x^2 - 4x + 2 =x^3 - 2x^2 - 2x +1
x? + 2x - 1 - 2x? - 4x + 2 x? - 2x? - 2x + 1
(x^3+2x-1) - (2x^2+4x-2) x^3+2x-1 - 2x^2 - 4x + 2 x^3 - 2x^2 + 2x - 4x - 1 + 2 x^3 - 2x^2 - 2x + 1
the plus and minus signs and indicators cancel out, meaning that the sum is 7/19-(a million/2) for addition (or subtraction) of fractions, the fractions choose a commonn base, and the backside consumer-friendly facto between 2 and nineteen is 38 so 7/19 could grow to be (7*2)/(19*2)=14/38, and a million/2 could grow to be (a million*19)/(2*19)=19/38 so we are left with (14-19)/38=-5/38 with the aid of fact 5 is a high-quality variety, your answer is -5/38
(x^3 + 2x - 1) - (2x^2 + 4x - 2) = x^3 + 2x - 1 - 2x^2 - 4x + 2 = x^3 - 2x^2 - 2x + 1
