x^(2) - 12x + 36

Look for two factors of '36', that add/subtract to '12'. ;-

1,36 ; 2,18; 4,9; 6,6.

The last pair 6 & 6 add to ;12;

Hence

(x 6 )(x 6)

Which signs????

Since '36' is positive(+), then both the signs are the same. They can be both negative , or both positive.

Since the sign in '12x' is hegative then they are both negative.

Hence

(x - 6)(x - 6) Done!!!!!

(x + 12)(x - 3)

That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (5 plus or minus the square root of 73) divided by 12. y = 1.128666978776461 y = -0.2953336454431275

x2-10x-24 = (x+2)(x-12) when factored

There is a formula for the difference of squares. If that's x2 - 144, the answer is (x - 12)(x + 12)
