Question

Enter the number that would make the following expression a perfect square. x^2-6x+?
For this part would it be 36?
And, Then factor the expression to a squared binomial.

Answer 1

you take half of -6 to get -3

then you square it to get 9

so instead of 36 it should be 9

Answer 2

it would factor to (x-q)^2 where q is the number that is half of the x-coefficient

Answer 3

or i should say (x+q)^2

Answer 4

Okay so would it be (x+9)^2?

Answer 5

no it should be (x-3)^2

q = -3 because -3 is half of -6

Answer 6

oh okay! well that makes sense. Thank you!
