Find the value of C that makes each a perfect square trinomial x^2+2x+c

x^2+2x+1

Step-by-step explanation:

x^2 +2x

Take the coefficient of x

2

Divide by 2

2/2 =1

Square it

1^2 =1

That is the value of c to make it a perfect square trinomial

x^2+2x+1

(x+1)^2

a. -0.3 > -0.33

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
