-x2(5x5 + 13)
26
the factor pairs are 1x35 & 5x7
the factor pairs are 1x35, 5x7
There aren't any common factors, which makes the GCF 1. This is meaningless to factor out, since it leaves the original equation. If you meant to write -5x7, that makes the common factor -x2 and leaves (5x5 + 13)
(x - 2)(x + 2)(x - 3)(x + 3)
The GCF of 26 and 32 is 2. 32=2^5 26=13x2 Note that the only common factor is 2 so it is the gcf.
First factor both numbers. 14=2x7 35=5x7 Take all the factors that are common in both numbers. 7 is the GCF Some numbers like 24 and 18 may have more. 24=2x2x2x3 18=2x3x3 Common to both are 2x3=6 6 is the GCF.
Since 7 is a factor of 28, it is automatically the GCF.
Since 12 is a factor of 96, it is automatically the GCF.
The greatest common factor (GCF) is: 14
Since 74 is a factor of 222, it is automatically the GCF.
4x4 + 13x2 + 36 is a quadratic in x2. The discriminant is 132 - 4*4*36 = -407. Since the discriminant is negative, the expression has no real roots and so it cannot be factorised (in the normal sense of the term).
