Question

find the zeros of quadratic polinomial x2 + 7x + 10 , and verify the identity relation ship b/w zeroes and coefficients
​

Answer 1

Step-by-step explanation:

x^2 +7x+10=0

x^2+5x+2x+10=0

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

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

x=-2 , x=-5

verify:

alpha+bita= -2+-5

=-7

=-b/a =-7/1 = -7

alpha×bita= -2×-5=10

=c/a= 10/1= 10
