I think the answer is (13-t)(13+t) because when you expand the brackets some of it cancells out like +169 - 169. As they are the same (but ones got a plus and ones got a minus) they cancel each other out. :)

T squared is T times T. T squared and T squared appears to be the addition of T squared with itself. That answer would be 2T squared or 2T^2

That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (19 plus or minus the square root of 1441) divided by 2t = 28.480252896102307t = -9.480252896102307

t2 - 36 = (t - 6)(t + 6) This pattern is often called the difference of squares.

T plus (or T minus) usually refers to a specified time, plus or minus however many minutes. So for example, when NASA launches the space shuttle, they have very specific launch times calculated down to the minute - 07:43 AM. So instead of referring to that specific time, when it may be sensitive information anyway, they refer to it as "T-time". Knowing this we can say that T plus 10 minutes is 07:53 AM, and T minus 10 minutes is 07:33 AM.

All that can be said, based on the available information is: t + v2

That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (1 plus or minus the square root of -191) divided by 24t = 0.0416666 repeating + 0.5758447900452189it = 0.0416666 repeating - 0.5758447900452189iwhere i is the square root of negative one.

NEVERMIND!

(t-7)/w = (-3-7)/-2 = -10/-2 = +5 ( minus over minus = plus)

(t + 3)(t - 15)Ask yourself, what factors of - 45 add up to - 12 ?t = - 3t = 15

n2 - 100t write t = (√t)2 = n2 - (10√t)2 = (n - 10√t)(n + 10√t)

That's one term. You need at last two to find an LCM. That factors to t(t + 2)(t + 2)

The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
