a and b are real numbers
We have the following expressions:
a² - b² = 9
a.b = 3
Question: what are the value(s) for a and b ?
Good luck! And try to be among the first ones!
a=5 b=4
5²=25 4²=16 25-16=9
in a rectangular triangle with hypotenuse = 5 and opposite side = 4 the adjacent side =3
Thanks Joachim for your prompt reply! You are right with a=5, b=4 for the first equation (a²-b²=9). But they are not OK for the second equation a*b=3 since 4*5= 20 !
May be you want to retry?
