Simplify the expressions 6x²+4(x²-1) x=

19x I think would be tbe answer.?

the simplification I believe is 4x^3+6^2-4x

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

i think is g(1)=-1.

hope that i can
