Question
Descartes's Rule of Signs: Let P be a polynomial with real coefficients. The number of positive real zeros of P(x) either is equal to the number of variations in sign in P(x) or is less than that by an even whole number. The number of negative real zeros of P(x) either is equal to the number of variations in sign in P(-x) or is less than that by an even whole number. c. Using Descarte's Rule of Signs, how many possible positive real zeros are there in P(x) = 6x -7x' -12x +3x + 2? d. Using Descarte's Rule of Signs, how many possible negative real zeros are there in P(x) = 6x* – 7x -12x +3x+2? e. Find ALL the real zeros of P(x)= 6x* - 7x-12x +3x+2
