Hi ! I have some problem with this below !

Subjected to a square which has two isosceles triangles.
One of them is: a triangle whose base is one of the sides of the square with base angles of 15.
The other is a triangle whose base is the side opposite the base of the triangle it first touches the apex of the triangle at the end of the first node.
Proved that the second triangle equilateral!

The prove must be geometric way , no trigonometric ! Please help me ! thanks all !

No , sorry !

abc triangle given:
let ac = t
and ab = 2t
and bc = Kt

Find the values of k for the triangle to be obtuse angle ???

Hi yehoram;

Welcome to the forum!

A polynomial needs to have non negative integer or whole number exponents.

Is not a polynomial. When you are factoring a polynomial you are trying to have polynomial factors.

This 

is

also negative ?????
