Question

25 +5 215-13
25-15 215 + 3
-
= a + 15b​

Answer 1

Answer:

Step-by-step explanation:

$a+b=25$

then a= $25-b$

ab=$150$

now, $(25-b)b=150$

$25b-b^2=150$

$b^2-25b+150=0$

$b^2-15b-10b+150=0$

$b(b-15)-10(b-15)=0$

$(b-10)(b-15)=0$

therefore, $b=10,15$

now put value of b in$(a=25-b)$

when we put $b =15,$ a becomes $10$

and when  $b=10$ , a becomes  $15$

$a=10,b=15$

$a=15,b=10$

answer

(if $a= 10, b=15,$

$a-b= 10-15 =-5)$

(if $a=15, b=10,$

$a-b=15-10 =5)$

hope it helps
