Question

the product of two numbers is 45 and there some 14 find the two numbers​

Answer 1

Answer:

the product of two numbers is 45

let,

the one number be =x

the second number=y

the product of two numbers=x(y) =45...... (1)

And, their sum =14

x+y=14

x=14-y....... (2)

sub eq 2 in 1

14-y(y) =45

14y-y^2=45

-y^2+14y-45=0

-(y^2-5y-9y+45)=0

y(y-5) -9(y-5) =0

(y-9) (y-5) =0

y-9=0 &y-5=0

y=9 or y=5

sub y =9 in eq 2

x=14-9=5

or

x=14-5=9

their products is 5(9) =45 or 9(5) =45

sum is 9+5=14 or 5+9=14
