Question

if two zeros of x cube minus 4 x square + 3 X + 12 are root 3 and minus root 2 find the remaining zero​

Answer 1

Step-by-step explanation:

for a cubic polynomial, x³-4x²+3x+12

let the roots be

$\alpha \\ \beta \\ \gamma$

then

$\alpha + \beta + \gamma = \frac{ - b}{a}$

3+(-2)+another root= 4

1+root=4

root=3

so the other root is 3

Answer 2

Answer:

zeros is a coefficient of x^3.
