Question

Find rational roots of the polynomial f (x) = 2x^2+x^2-7x-6
​

Answer 1

Answer:

roots of polynomial is 2/3 and 3

Step-by-step explanation:

f(x) = 2x² + x² - 7x - 6

3x² - 7x - 6

3x² -(9 - 2)x - 6

3x² - 9x + 2x - 6

3x(x - 3).2(x - 3)

(3x - 2)(x - 3)

3x - 2 = 0 , x - 3 = 0

3x = 2 , x = 3

x = 2/3 , x = 3
