Question

(a+b)²= ?
a)a²-2ab-b²
b)a²+2ab+b²
c)(a-b) (a+b)
d)a²-2ab+b²
​

Answer 1

Answer: b)a²+2ab+b²

Step-by-step explanation:

This is an algebraic equation.

(a+b)² = (a+b)*(a+b)

(a+b)*(a+b) = a² + ab + ba + b²

(a+b)*(a+b) = a² + b² + 2ab

(a+b)² = a² + b² + 2ab

These two literals a and b represent two terms in algebraic form. The sum of them is written a+b as in mathematics. It is an algebraic expression and also a binomial.
