Raise x to the 2nd power
ali2x2
  • ali2x2
then you Simplify 2x2+4x - 2
ali2x2
  • ali2x2
Pull out like factors : 2x2 + 4x - 2 = 2 • (x2 + 2x - 1)
ali2x2
  • ali2x2
Factoring x2 + 2x - 1 so then its coefficient is 1 .
ali2x2
  • ali2x2
then the middle term is, +2x so its coefficient is 2 .
ali2x2
  • ali2x2
The last term, the constant, is -1
ali2x2
  • ali2x2
then we multiply
ali2x2
  • ali2x2
1 • -1 = -1
ali2x2
  • ali2x2
then we find two factors of -1 whose sum equals the coefficient of the middle term, which is 2 .
ali2x2
  • ali2x2
-1 + 1 = 0
ali2x2
  • ali2x2
\[ 2 • (x^2 + 2x - 1)\]
ali2x2
  • ali2x2
thats the final answer
