Divisors 7779

Two numbers are guessing. The second number is five times greater than the first number, and the square of the first number is equal to 3/5 of the second number. Find the sum of the two numbers and all its divisors.

Correct answer:

s1 =  18
d1 = 1, 2, 3, 6, 9, 18
s2 =  0
d2 =  

Step-by-step explanation:

b = 5a a2 = 3/5 b  a2=3/5⋅ 5⋅ a  a2=3/5⋅ 5⋅ a a2−3a=0  p=1;q=−3;r=0 D=q2−4pr=32−4⋅1⋅0=9 D>0  a1,2​=2p−q±D​​=23±9​​ a1,2​=23±3​ a1,2​=1.5±1.5 a1​=3 a2​=0  b1​=5⋅ a1​=5⋅ 3=15 b2​=5⋅ a2​=5⋅ 0=0  s1​=a1​+b1​=3+15=18

Our quadratic equation calculator calculates it.

d1​=1,2,3,6,9,18
s2​=a2​+b2​=0+0=0
