Q. Write a polynomial f(x) that satisfies the given conditions.Polynomial of lowest degree with zeros of −61 (multiplicity 2 ) and 43 (multiplicity 1 ) and with f(0)=3.f(x)=
Identify Zeros: To find the polynomial of the lowest degree with the given zeros, we need to write down the factors corresponding to each zero. The zero at −(1/6) with multiplicity 2 means we will have a factor of (x+1/6)2. The zero at (3/4) with multiplicity 1 means we will have a factor of (x−3/4).
Write Factors: Now we write down the factors as part of the polynomial: f(x)=(x+61)2⋅(x−43)
Expand Factors: Next, we need to expand the factors to write the polynomial in standard form: f(x)=[(x+61)(x+61)]⋅(x−43)
Combine Terms: Expanding the squared factor:f(x)=[x2+(61)x+(61)x+(361)]⋅(x−43)f(x)=[x2+(31)x+(361)]⋅(x−43)
Adjust Constant Term: Now we expand the remaining factors:f(x)=x3−43x2+31x2−41x+361x−361⋅43f(x)=x3−43x2+31x2−41x+361x−1443f(x)=x3−129x2+124x2−123x+361x−481

Adjust Constant Term: Now we expand the remaining factors:f(x)=x3−43x2+31x2−41x+361x−361⋅43f(x)=x3−43x2+31x2−41x+361x−1443f(x)=x3−129x2+124x2−123x+361x−481Combine like terms:f(x)=x3−125x2−122x−481To ensure that f(0)=3, we need to adjust the constant term. Since the constant term is currently −481, we need to add 3+481 to it to make f(0) equal to 3.
