An integer

An integer is 17 more than five times another. If the product of the two integers is -6, then find the integers.

Correct answer:

a =  2
b =  -3

Step-by-step explanation:

a = 17 + 5b ab = 6  (17+5 b) b=6  (17+5 b) b=6 5b2+17b+6=0  p=5;q=17;r=6 D=q24pr=172456=169 D>0  b1,2=2pq±D=1017±169 b1,2=1017±13 b1,2=1.7±1.3 b1=0.4 b2=3  b1/N b2 N  a=17+5 b2=17+5 (3)=2

Our quadratic equation calculator calculates it.

b=b2=(3)=3   Verifying Solution:  P=a b=2 (3)=6
