Question

find the sum of the zeroes of quadric polynomial x^2+7x+10​

Answer 1

Answer:

7

Step-by-step explanation:

to expand your equation i got (x+5)(x+2)

so the sum of the zeroes of your quadric polynomial is 5+2=7

Answer 2

Answer:

= -7

Step-by-step explanation:

============================================

=> 1st Method :

p (x) = x2+7x+10

a = 1 , b = 7 , c = 10

Let the zeroes of the given Polynomial be x and y

Sum of zeroes(x + y) = -b/a = -7/1 = -7

============================================

2nd Method : (By factorisation)

p(x) = x2+7x+10

= x2+5x+2x+10

= (x+5)(x+2)

For Zeroes , p(x) = 0

x = -5 , -2

Sum Of Zeroes = (-5)+(-2) = -7

============================================
