Answer:
+10
Step-by-step explanation:
by factorisation
x^2+7x+10
=10 , 7
5 and 2 satisfies the condition of factorisation
that is, 5*2=10 , 5+2=7
x^2+5x+2x+10=0
by taking x and 2 as common
x(x+5)+2(x+5)
=(x+2)*(x+5)=0
x+2=0
x=-2
x+5=0
x=-5
now we got the two roots or zeros of the equation, product of them implies
(-2)*(-5)
