n2 - 100t write t = (√t)2 = n2 - (10√t)2 = (n - 10√t)(n + 10√t)
15t2 squared-t-15t+3=15t squared-14t+3
28 t2 - 17 t - 3 = (7t + 1) x (4t - 3)
(t + 3)(t - 15)Ask yourself, what factors of - 45 add up to - 12 ?t = - 3t = 15
(the square root of 19 - t)(t + the square root of 19)
(t + 1)(2t - 3)
n2 - 100t write t = (√t)2 = n2 - (10√t)2 = (n - 10√t)(n + 10√t)
The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
(6x + t)(3x + t)
15t2 squared-t-15t+3=15t squared-14t+3
t2+ t - 42 it can't be simplified anymore
28 t2 - 17 t - 3 = (7t + 1) x (4t - 3)
(t + 3)(t - 15)Ask yourself, what factors of - 45 add up to - 12 ?t = - 3t = 15
4x-4y-ty+xt = 4x+tx-4y-ty = x(4+t) - y(4+t) = (x-y)*(4+t)
(the square root of 19 - t)(t + the square root of 19)
t2 - 36 = (t - 6)(t + 6) This pattern is often called the difference of squares.
The GCF is t.
