Question

factor 16-6x-x^(2)
what does the whole solution look like?

Answer 1

@aimmeBgood are you here?

Answer 2

yeah

Answer 3

let solve your problem together........does you know about middle term spilt

Answer 4

Eh uzumakhi..

We have Nurroto here on the openstudy..

Answer 5

sort of

Answer 6

its naruto not nurroto

Answer 7

I will advise you to take the minus common and then solve it will ease the problem @uzumakhi and carry on..

Answer 8

Like this :

\[-(x^2 + 6x - 16)\]

Answer 9

what about this
16 - 8x + 2x - x^2

Answer 10

Carry on I said..

Answer 11

16 - 8x + 2x - x^2
8(2 - x) + x(2 - x)
(8+x)(2-x)

Answer 12

ok. so does the both the 2 and 8 come from the same number or is the 8 from the 16 and the 2 from the 6?

Answer 13

the solution is -2 and 8

Answer 14

but where does the 2 and 8 come from in the equation?

Answer 15

the first is 16 and second is -6x
we have to select to numbers in such a way that if we multiple them then we got first number or number which is not having x and if we add them we got second number or number with x
this is known as middle term split method
we write -6x = -8x + 2x

Answer 16

have u understand @aimmeBgood
