Simplify the expression –2(p + 4)2 – 3 + 5p. what is the simplified expression in standard form?

–2p2 – 11p – 35
2p2 + 21p + 29
–2p2 + 13p + 13
4p2 + 37p – 67

Step-by-step explanation:

Here, the given expression is,

=

=

=

=

Which is the required simplified expression in standard form.

⇒ First option is correct.

< 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
