What value of c makes the trinomial below a perfect square x2 + 5x + c

Step-by-step explanation:

The given expression is

               ...... (1)

If an expression is defined as , then we need to add in it, to make it perfect square.

In the expression , b=5.

Add in to make it perfect square.

     .... (2)

On comparing (1) and (2) we get

Therefore, is a perfect square if .

answer: (1,3) and (-2,0) i think.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
