The GCF is 27.
a2 + 28a + 27 = 0 (a + 1)(a + 27) = 0 a = -1 or -27 However, the second line is the factorised form, the third is what a is equal to
With great difficulty not knowing if 6x and 27 are plus or minus
The grouping of the factors of w^2 + 30w + 81 (a perfect square) is (w + 27) and (w + 3)3 is a prime factor of 27, 30 and 81 but without two terms to compare, there won't be a GCF (not gfc)
Since 3 is a factor of 27, it is automatically the GCF of 3 and 27
3(2x - 3)(x + 3)
(x-3)(x-9) = 0
The given expression can be simplified to: 3X squared +27
-27
9
Since 27 is a factor of 54, it is automatically the GCF.
x2 - 6x - 27 = (x-9)(x+3)
The GCF is 27.
27x2 - 90x + 27 = 9*(3x - 1)*(x - 3)
9p + 27 = 9(p + 3)
27 squared is 27 x 27 27 cubed is 27 x 27 x 27 The exponent shows how many times the base is used as a factor.
(a + 9)(a - 3)
