Find all the values of x that are NOT in the domain of g. If there is more than one value, separate them with commas g(x)=x^2+9x+14
X^2+7x+12

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

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

your answer is 125y5
