Question

fill in the blank with a number to make the expression a perfect square. type only a numberw^2 - 12w=

Answer 1

We will solve as follows:

`w^2-12w+\alpha=0`

Here alpha is the blank space, we then will solve by factoring:

`(w+b)(w+c)=w^2-12w+\alpha`

*Two numbers that added equal -12 can be -10 and -2 and when multiplied they equal to 20, then we will have that alpha will be equal to:

`w^2-12w+20=0`

Then, the final expression is:

`w^2-12w=-20`
