Answer 1

Answer:

let the triangle be ABC and sides be a,b,c

Step-by-step explanation:

a+ b +c =5x^2 +3x -1

a= 2x-5+7x^2

b= 3x^2+4-2x^3+x

c=?

a+ b +c= 5x^2 + 3x -1

2x-5+7x^2 +3x^2+4-2x^3+x +c =5x^2+3x-1

10x^2 +3x -1-2x^3 +c=5x^2+3x-1

c= 5x^2+3x-1-10x^2-3x+1+2x^3

THEREFORE,

c=2x^3-5x^2 (or) x^2(2x-5)
