Answer:
To find the answer in 2 ( a - b) + 3 (a + b), if a = 2 and b = 3.
Solution : 2(a - b) + 3(a + b) ……#1.
If a = 2 and b = 3, then 2 = a and 3 = b respectively.
Substituting the values of “2” and “3” in #1, we have
a (a - b) + b (a + b)
= a^2 - ab + ab + b^2,
= a^2 + b^2…….#2.
Substituting the given values of “a” and ”b” in #2 will give
2^2 + 3^2 = 4 + 9 = 13.
The answer is “13”.
