Question

what is the factorization of -x2+11+26

Answer 1

I assume you mean 11x, right?

First, factor out a -1:

\( -1(x^2 - 11x - 26) \)

Answer 2

would it be -1(x+13)(x+2)

Answer 3

Now find 2 numbers that multiply to -26 and add to -11.

Answer 4

No. Your signs don't work out.

Answer 5

2,13

Answer 6

Careful. The numbers are -13 and 2.

Answer 7

oh okay i always get missed u with my signs

Answer 8

so -1(x-13)(x+2)

Answer 9

\( -1(x - 13)(x + 2) \)

You can leave it like that, or you can multiply the -1 into one of the two factors:

\( (-x + 13)(x + 2) \) or \((x - 13)(-x - 2) \)

Answer 10

oh okay ima close it and open another one kay
