Which polynomial function has a root of 1 with multiplicity 2 and a root of 6 with multiplicity 1?
Of(x) = (x - 1)(x-6)
O f(x) = 2(x - 1)(x-6)
Of(x) = (x - 1)(x - 1)(x-6)
Of(x) = (x - 1)(x-6)(x-6)

correct answer:

b.(19,-2)

step-by-step explanation:

si si si

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
