2x^8 -16x^7 +10x^6 = 2x^6(x^2 - 8x + 5)
4x+7-8x=17-4x+7=17-4x=10x = -5/2
This is not factor-able.
(5x - 7)(x + 3)
8x+7=55 8x=55-7 8x=48 x=48/8 x=6

2x^8 -16x^7 +10x^6 = 2x^6(x^2 - 8x + 5)
4x+7-8x=17-4x+7=17-4x=10x = -5/2
Oh, let's paint a happy little equation here! To simplify this expression, we first distribute the -3 to both terms inside the parentheses, giving us 7 - 12 + 6x - 10x. Next, we combine like terms to get -5 - 4x. Remember, there are no mistakes, just happy little math lessons!
If that was - 10x + 21, it would factor to (x - 3)(x - 7) If that was + 10x + 21, it would factor to (x + 3)(x + 7) As it is, the solutions are irrational.
45
If that's + 10x + 21, the answer is (x + 7)(x + 3)
This is not factor-able.
(x - 7)(x - 3)
(5x - 7)(x + 3)
This is not right as 10x7 is 70 and 8x13 is 104 the equals means they should both have the same answer. hope this helps ;)
(x - 7)(x - 3)
