Answer:
c = 9/16
Step-by-step explanation:
step1
(a-b)²
a² - 2ab + b²
here a = x
b = ?
so
x² - (2)(x)(?) + ?²
Now we can see that -(2x)? = -3x/2
-2x? = -3x/2
cancel -x on both sides
2? = 3/2
? = 3/2 * (2)
? = 3/4
so b = 3/4
step2
(x² - 3x + 9/16) = (x-3/4)²
so from the expression we can see that C = 9/16
