evaluate alpha^-1 + beta^-1 if alpha and beta are the zeros of polynomial f(x)=9x^2-3x-2 About the author Camila

Step-by-step explanation: f(x) = 9x²-3x-2 acc to ques , alpha and beta is the zeros of polynomial f(x) so, alpha + beta = -(-3)/9 = 1/3 and apla × beta = (-2)/9 we have to find 1/(apha) + 1/(beta) = [(apha) + (beta)]/(apha)×(beta) = 1/3÷(-2)/9 = -3/2 is the answer.. Reply

Step-by-step explanation:f(x) = 9x²-3x-2

acc to ques , alpha and beta is the zeros of polynomial f(x)

so, alpha + beta = -(-3)/9 = 1/3 and apla × beta = (-2)/9

we have to find

1/(apha)+1/(beta)=[(apha)+(beta)]/(apha)×(beta)=1/3÷(-2)/9=-3/2istheanswer..
