Question

Write a polynomial expression for the perimeter of a triangle whose sides have the following lengths. x + 8, 3x^2+4x, x^2-3x+6

Answer 1

lets collect like terms (which means terms with the same x variable)
x + 8+ 3x^2+4x+ x^2-3x+6
collecting all terms with only a x
2x+8+3x^2+x^2+6
then collect all numbers
2x+14+3x^2+x^2
then all the x^2
2x+14+4x^2

hope that make sense
