As written, -5x + 9x = 4x
4x - 4 = 4(x - 1)
If that's -5x2 + 9x - 4, that factors to -(x - 1)(5x - 4)

36 because: 4,8,12,16,20,24,28,32,36,40 9,18,27,36....or...... 4x9=36 9x4=36
32 because 9x4=36 36-4=32
GCF of variables with exponents The GCF is the common variable with smallest exponent. example 9x4 - 27x6 the gcf is 9X4 because: 9x4 (1-3x2) = 9x4 - 27x6 In the same way: X5 is the GCF of X10 + x5 -x6 Because X5 ( X5 + 1 -x1) = X10 + x5 -x6 Remember the exponent rule if you are multiplyin the same base, you keep the base and add the exponents Hope this helps Btw this does not help me! anna
