Which shows a perfect square trinomial? 50 y squared minus 4 x squared 100 minus 36 x squared y squared 16 x squared + 24 x y + 9 y squared 49 x squared minus 70 x y + 10 y squared

100-36x^2y^2

Step-by-step explanation:

100-36x^2y^2 =

(10-6xy)(10+6xy)

Because x^2-y^2 = (x+y)(x-y)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

1. minimum

2. 6400

3. eight
