Question

I can't figure out how to factor this (16x^2 - 8x + 1)?

Answer 1

(4x-1)(4x-1)

Answer 2

Can you explain the steps?

Answer 3

the way i figured out was first starting with the +1, means that the single number must be +/- 1 as there are no other number that can be times together to get 1

Answer 4

from there because it was -8x i knew that both 1's must be negative

Answer 5

so when you listed all of the factors of 16 i picked 4+4 but i could not figure out how to make that negative?

Answer 6

for -8

Answer 7

(4x-1)(4x-1)
16x^2 -4x -4x +1

Answer 8

when cancelling it out
