Factoring 4x²-4x+1
The first term is, 4x2 its coefficient is 4 .
The middle term is, -4x its coefficient is -4 .
The last term, "the constant", is +1
- Step-1 : Multiply the coefficient of the first term by the constant 4 • 1 = 4
- Step-2 : Find two factors of 4 whose sum equals the coefficient of the middle term, which is -4 .
-4 + -1 = -5
-2 + -2 = -4 That's it
- Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and -2
4x2 - 2x - 2x - 1
- Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (2x-1)
Add up the last 2 terms, pulling out common factors :
1 • (2x-1)
- Step-5 : Add up the four terms of step 4 :
(2x-1) • (2x-1)
Which is the desired factorization
hope this answer will work.....
Thank you
