Question

12 6 92. If (a+b) = 12 and a? - b2 = -24 then the value of a-b is : cu - 2 (2) 2 ) (1) (3) 144 4) 36​

Answer 1

Step-by-step explanation:

given that

a+b =12

a^2 - b^2 = -24

a^2 -b^2 = (a+b) (a-b)

or -24 = 12(a-b)

or (a-b) = -2

Answer 2

Answer:

a+b=12

a^2-b^2=-24

we know a^2-b^2=(a+b)(a-b)

thus

-24=(a+b)(a-b)

-24=12*(a-b)

-24/12=(a-b)

thus

(a-b)=-2
