Factor to find the roots.
(x+5)(x-1)=0
Proof:
5-1=4
5*-1=-5
Then apply the Zero Product Property.
(x+5)=0
x=-5
(x-1)=0
x=1
Roots: x=-5, x=1
Answer:
The converse of Pythagorean Theorem states:
<em>If the square length of the longes side of a triangle is equal to the sum of the squares of the other two sides, then it's a right triangle.</em>
<em />
We use the converse of Pythagorean Theorem to prove that a triangle is a right triangle. It's like the inverse use of the theorem. Often, this theorem is used to find the length of a side of a triangle when we already know it's a right triangle. However, when we don't know that is a right triangle, we use the converse to prove it.
