Question

find the sum of zeros quadratic polynomial x2+13x +42​

Answer 1

Step-by-step explanation:

p (x) = x2 +13x + 42

a = 1 , b = 13 , c = 42

sum of zeroes = -b/a

=> -(13)/1 = -13

Answer 2

Answer:

x2+13x+42=0

sum of zeroes or roots is equals to = -b/a

here b=13, a=1

sum of zeroes = -13/1= -13
