Question

find the sum of zeroes of polynomial 5x³+5x²+5x+10​

Answer 1

Answer:

sum of zeroes of polynomial = (-1)

Step-by-step explanation:

SOLUTION:

We have p(x) = 5x³ + 5x² + 5x +10 where a=5, b=5, c=5, d=10 (ax³ +bx² + cx +d)

and we know that SUM OF QUADRTIC POLYNOMIAL:

                   α + β + γ = (-b/a)

therefore,   α + β + γ = (-5)/5

                   α + β + γ = -1
