Why, yes, indeed, it has!
Look at the factors:
x2 - 8x + 16 = (x - 4)2 = (x - 4)(x - 4).
If you multiply it out, you will see that it is so.
Note that ' (x - 4) ' appears twice in the factorisation.
That is what we mean, by a 'repeated factor'.
y = x2 - 4x + 4 can be factored into y = (x-2)(x-2) The repeated factor is 2.
( a2 ) ( a2+1 )
x+11x+30(x+5)(x+6)
(x + 5) (x - 4)
4(x+8)
y = x2 - 4x + 4 can be factored into y = (x-2)(x-2) The repeated factor is 2.
False
Factor the polynomial x2 - 10x + 25. Enter each factor as a polynomial in descending order.
