What binomial expressions are factors of4x^3 + 9x^2 - x - 6(multiple choice)answers: a. x - 2b. x - 1c. x + 1d. x + 2

C and D

Step-by-step explanation:

The factor theorem tells us that if we evaluate a polynomial at and the answer is 0, then is a factor of .

So we can check,

from

from

from

and

from

and see which gives us 0. For those that give 0, that respective expression is a factor of the binomial expression given.

The last 2 gives us 0. Hence, and are factors of . Answer choices C and D are 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
