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
The GCF is 27.
With great difficulty not knowing if 6x and 27 are plus or minus
Since 3 is a factor of 27, it is automatically the GCF of 3 and 27
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)
the greatest common factor for 27 and 32 is 1
(w + 3)(w^2 - 3w + 9)
Since 27 is a factor of 54, it is automatically the GCF.
The GCF is 27.
a2 + 28a + 27As it stands, there's no answer, because there's no question here.The expression can be factored: (a+1) x (a+27) , but that's just a different way to writethe same expression, and there's still no question.If we were told that some number is equal to this expression, then we could calculatethe value of 'a' that makes that a true statement.For example, if this expression is 'zero', then ( a = -1 ) and ( a = -27 ) are both true.But so far, there's no question asked, so there's no answer.
9p + 27 = 9(p + 3)
(a + 9)(a - 3)
The GCF is 9.
a2 + 12a + 27 = (a + 3)(a + 9)
(2y + 3)(4y2 - 6y +9)
(r + 9)(r + 3)
33 = 2726 = 647 x 13 = 91
(5x - 3)(7x + 9)
