Answer:
let two numbers be x & y
x-y=3 ..........(1)
by question
xy=70
x=70/y..... ..............(2)
Explanation:
putting the value of x in equation 1,we get
70/y-y=3
(70-y²)/y=3
70-y²=3×y
70-y²=3y
0=y²+3y-70
y²+10y-7y-70=0
y(y+10)-7(y+10)=0
(y+10)(y-7)=0
either
y=-10(rejected)
or
y=7
:.y=7
putting the value of x in equation 1
x-7= 3
x=3+7=10
therefore required no is 3 and10
149
Answer:
7 and 10
10-7=3
10×7=70
7²= 49
10²= 100
100+49 = 149
