Question

Can someone help me

3. Solve by using the perfect squares method.

x2 – 12x + 36 = 0


–18
–6
6
18

Answer 1

So what number multiplied by itself = 36?
and at the same time..that same number should also add to itself to make -12

What is your number?

Answer 2

6

Answer 3

Hmm....well the answer to MY question is not 6

but the answer to the ACTUAL question IS 6 lol

Answer 4

So to my question...what number is it? it would be -6

-6 times -6 is indeed 36...and -6 + -6 is again indeed -12
so we have

\[\large (x - 6)^2 = 0\]

and the answer to that IS 6
