Question

(a) Find the rational zeros and then the other zeros of the polynomial function f(x) = x2 - 7x2 +9x +9, that is, solve f(x) = 0. (b) Factor f(x) into linear factors (a) Select the correct choice below and fill in any answer box(es) within your choice (Type an exact answer, using radicals as needed. Simplify your answer. Use a comma to separate answers as needed.) OA. There are no rational zeros. The other zeros are B. There is only one rational zero, . and the other zeros are C. There are only rational zeros and they are (b) The factorization of f(x) into linear factors is (Type an exact answer, using radicals as needed. Simplify your answer.

anyone know how to do this?

Answer 1

solution Given, finna х ам-+91 + 0 (а) қа, () ero у эм + 9 - 6 at n= 3; 22-63 + 2 + 9 о Hence, (4-3) is a factor of fans = x27x²gr ty for ойлох factors : яа ) ~ 9 яну (5 м -3 ) и 3,2 (+) - 4 1 » п + 12 и —4 (+) - 3 + 64 (4) Hence, Г) = (х +3) (- 4 и 3) Now, 4. — 20 (4) + J-4) 4х тусг) и २ it 91 | tv х 4 + J28 4+ 2ја х - 2+ Ja 2

Hence, •B. There is only one rational zero, 3 and the other zeros are 9 +57 , 2-57 (b) The factorization of freil into linear factor is : f(n) = (2-3) (n²-4 nrg) fmo = (2-3) ( ^_(2+57)) (~- (2-57)) oR frons = (x+3)(x-2-57) (-2+57) Answer
