The GCF is x5
Since 19x^3 is a factor of 38x^5, it is automatically the GCF.
Factor as : (x+9)(x+10) using the first terms ( x terms) multiply to x2; the last terms multiply to 90; the sum of 9x + 10 x = 19x
(3x + 1)(x + 6)
(x + 12)(x + 7)
4x3 - 19x2 - 5x =x (4x2 - 19x - 5) =x (4x + 1) (x - 5)
Since 19x^3 is a factor of 38x^5, it is automatically the GCF.
x^2-19x+90 (x-9) (x-10)
(x - 3)(7x + 2)
(3x + 7)(x + 4)
(x - 10)(x - 9)
Factor as : (x+9)(x+10) using the first terms ( x terms) multiply to x2; the last terms multiply to 90; the sum of 9x + 10 x = 19x
