Question

Find the sum of zeroes ofx^3+4x^2-5x-2=0​

Answer 1

Answer:

-4

Step-by-step explanation:

$Given, \\ x^3+4x^2-5x-2=0 \\\\ it \ is \ of \ the \ form \ ax^3+bx^2+cx+d=0 \\ a=1,b=4,c=-5,d=-2 \\\\ => sum \ of \ zeroes= \frac{-b}{a} \\\\ =>sum \ of \ zeroes=\frac{-4}{1} =-4$

Answer 2

Answer:

sum of zeroes = -b/a

sum of zeroes = -4/1

sum of zeroes = -4
