(the square root of 19 - t)(t + the square root of 19)

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 2 t = 28.480252896102307 t = -9.480252896102307

19 x a x a x b = 19a2b

t+t=2t and t*t= t squared you would only get t squared if you multiplied

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

19 squared is 361 361

19 squared = 19 x 19 = 361

(4x - t2) = [(2√x)2 - t2] (This is now the difference of squares) = (2√x - t)(2√x + t)

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

x2+x-380 = (x+20)(x-19) when factored

_t(5t squared t+)

7 squared and 11 squared have no common factor greater than 1.

15t2 squared-t-15t+3=15t squared-14t+3

52 is not a factor of 325. 5 squared is a factor of 325.
