Question

If A = a-b.B = a+b and C = 3a? - 2b2, then AB+C = ? ​

Answer 1

Step-by-step explanation:

if A=a.-b.B=a+b and C=3a -2b2,then AB+C=1

Answer 2

Answer:

we know that

A=a-b,B=a+b and C=3a

then,AB+C=?

substitute the values

(a-b).(a+b)+3a

-b and +b cancel

remaining

a×a+3a

a^2+3a

therefore answer is a^2+3a
