Question

if A = a2 + 2ab + 4, B= 5a2 +9 ab - 10, C= -9a2 -4ab + 14 The value of A+B+C IS

Answer 1

Answer: The value of A+B+C IS 3a2+7ab+8

Step-by-step explanation:

Given,

A = a2 + 2ab + 4

B= 5a2 +9 ab - 10

C= -9a2 -4ab + 14

Substitute A,B,C value in A+B+C ,

Add the values

A+B+C=a2 + 2ab + 4+5a2 +9 ab - 10+-9a2 -4ab + 14

A+B+C=3a2+7ab+8

Hence. we get the solution. The value of A+B+C IS 3a2+7ab+8
