Question

Find a²-b² if a+b =8 , a-b=3​

Answer 1

Answer:

Answer=24

Step-by-step explanation:

given,

a+b =8

a-b=3

we have to find,

a²-b²

we know that,

a²-b²=(a+b)(a-b)

a²-b²=(8)(3)

a²-b²=8x3

a²-b²=24.

Hope this helps you.

Answer 2

Step-by-step explanation:

a+b =8

a-b =3

then (a+b)*(a-b) = a² - b²

so a²- b² = 8*3

a²-b²=24
