t+t=2tand t*t= t squaredyou would only get t squared if you multiplied
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
The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
cos(t) - cos(t)*sin2(t) = cos(t)*[1 - sin2(t)] But [1 - sin2(t)] = cos2(t) So, the expression = cos(t)*cos2(t) = cos3(t)
15t2 squared-t-15t+3=15t squared-14t+3
(6x + t)(3x + t)
_t(5t squared t+)
(t + 1)(2t - 3)
2t
28 t2 - 17 t - 3 = (7t + 1) x (4t - 3)
72 = 49.72 + t = 49 + t
t+t=2tand t*t= t squaredyou would only get t squared if you multiplied
(t + 3)(t - 15)Ask yourself, what factors of - 45 add up to - 12 ?t = - 3t = 15
(3t + 1)(t + 5)
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. :)
t2 - 36 = (t - 6)(t + 6) This pattern is often called the difference of squares.
