We want to for the given expression. To do so, we will first identify
b. In a quadratic trinomial,
b is the linear , which is the number that is multiplied by the
x-variable.
x2+24x+c
Now, we will calculate
(2b)2. Since we have that
b=24, we can calculate the value of
(2b)2 by substituting
24 for
b.
When the value of
c is
144 our expression is a .
x2+24x+144
Now we can write this expression as the square of a binomial.
x2+24x+144
x2+24x+122
x2+2(x)(12)+122
(x+12)2
