Question

An isosceles triangle has sides represented by the expression given in the figure below. What is the perimeter of the triangle?                                                                                                                                      

            One side is 3X^2 + 5x -4 and the other is 2x^2 -*x + 3 It does n't give the 3rd side.

Explanation / Answer

You should be able to combine like terms, depending on what the missing * number is in front of your x. Since I don't have the picture, I don't know if the 2 sides you have are the 2 isosceles sides and there are congruent or if one of them is one of the isosceles sides and the other is the non-isosceles side. I think the problem will give you one of the isosceles sides and one of the non-isosceles.

In that case, just add together one isosceles side + the same amount for the missing isosceles side and the other side. For example, if 3x2+5x-4 is the isosceles side, then add 3x2+5x-4 +3x2+5x-4 to get 6x2+10x-8 and then add that to the last side 2x2-*x+3 to get 8x2 +(10 - *)x -5. If the 2x2-*x+3 side is the isosceles one, you would add it to itself (like terms only) and then add that result to the first side 3x2+5x-4.
