Question

X2 - __________x + 144

Answer 1

Answer:

the blank =24x

Step-by-step explanation:

Assuming the expression is x^2 - ________x +144,

you can tell that this is in the form of a^2 +2ab+b^2.

If the "a" is squared, you would get x^2. And if the "b" was squared then you would get b^2.

So as the result, the expression is

(x-12)^2= x^2-24x+144
