Answer 1

Answer:

Step-by-step explanation:

x²+7x+10 = 0

x² + 2x+5x+10 = 0

x(x+2)+5(x+2)=0

(x+2)(x+5)=0

x+2 = 0             x+5 = 0

x=-2                   x==5

Zeroes of this equation are  = -2 ,-5

RELATION BETWEEN THE ZEROES AND THEIR COEFFICIENTS =>

a=1 , b=7 , c=10

Sum of zeroes  =-b/a                      Product of zeroes = c/a

-2+(-5) =  -7/1                                          -2*-5 = 10/1

-7 = -7                                                     10=10
