What is the completely factored form of f(x)=x^3+4x^2+7x+6? f(x)=(x+2)(x−(−3+i10−−√−(−3−i10−−√) ) f(x)=(x+2)(x−(−1+i2√−(−1−i2√)) f(x)=(x−2)(x−(−1+i2√−(−1−i2√)) f(x)=(x−2)(x−(−3+i10−−√−(−3−i10−−√) )

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
