Factoring polynomials
8x - 16
8(x-2)
GCF:8
to get the x divide x and the GCF
to get the 2 divide 16 to 8
7 x + 49
7(x-7)
GCF:7
to get the x divide x and the GCF
to get the 2 divide 49 to 7
x2 -16
(x+4)(x-4)
take the S.Q of x2 which is x
take the S.Q of 16 which is 4
6 x - 24
6(x-4)
GCF:6
to get the x divide x and the GCF
to get the 4 divide 24 to 6
9x - 81
9(x - 9)
GCF:9
to get the x divide x and the GCF
to get the 9 divide 81 to 9
8x2 - 48x
8x(x-6)
to get 8x get the GCF first which is 8 and you get the x because they have both x
divide 8x2 to 8x to get the x
and divide 48 and 8 to get 6
x2 - 25
(x-5) (x + 5)
take the S.Q of x2 which is x
take the S.Q of 25 which is 5
x2 + 5 + 6
(x+2) (x+3)
5x2 - 25x
5x(x-5)
to get 5x get the GCF first which is 5 and you get the x because they have both x
divide 5x2 to 5x to get the x
and divide 25 and 5 get 5
x2 + 12 +35
(x+7)(x+5)
get the 1st factor which is x
now get the factor for 35 which is 7x5
then plus it 7+5 is 12
9x2 - 24
(3x - 6) (3x + 6)
S.Q OF 9 is 3
S.Q of x2 is X
S.Q of 24 is 6
x2 + 64
(x + 8) (x - 8)
take the S.Q of x2 which is x
take the S.Q of 64 which is 8
x2 + 8 + 16
(x+4) (x+4)
get the 1st factor which is x
now get the factor for 16 which is 4x4
then plus it 4+4 is 8
x2 + 22+ 121
(x+11) (x+11)
get the 1st factor which is x
now get the factor for 121 which is 11x11
then plus it 11+11 = 22
4x2 + 81
(2x+9) (2x - 9)
S.Q OF 4 is 2
S.Q of x2 is X
S.Q of 81 is 9
X2 + 17 + 65
(x + 13) (x + 5)
get the 1st factor which is x
now get the factor for 65 which is 13 x5
then plus it 13 + 5 = 17
x2 + 9 + 18
(x+6)(x+3)
get the 1st factor which is x
now get the factor for 18 which is 6x3
then plus it 6+3 is 8
x2 - 8
(x-2)(x+2)
take the S.Q of x2 which is x
take the S.Q of 8 which is 2
x2 + 36 + 155
(x+31)(x+5)
get the 1st factor which is x
now get the factor for 155 which is 31 x 5
then plus it 31 + 5= 36
(x+7) (x+6)
get the 1st factor which is x
now get the factor for 42 which is 7 x6
then plus it 7+6=13
