Find the zeros of polynomial functions and solve polynomials equations. f(x)=x^3-64

we are given

Since, we have to find zeros

so, we can set f(x)=0

and then we can solve for x

We will add both sides 64

Take cube root both sides

...........Answer

answer: sorry i can't you.

step-by-step explanation:

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
