Question

find the zeros of quadratic polynomial X square + 7 x + 10 and verify the relation between the zeros and the coefficient​

Answer 1

x²+7x+10=0

x²+5x+2x+10=0

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

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

x=-2, -5

sum of roots=-2-5

sum of roots=-7

also,

sum of roots=-b/a

sum of roots=-7/1

product of roots=-2*-5

product of roots=10

also,

product of roots=c/a

product of roots=10/1
