Question

(a+5)^2 simplify or expand by using suitable identity​

Answer 1

Answer:

(a+5)(a+5)

I am not sure about the answer

Answer 2

Your Answer:

The identity used here is

(a+b)² = a² + b² +2ab

So, Expanding by this algebraic Identity.

(a+5)²

= a² + (5)² +2a(5)

= a² + 25 + 10a

So, the expanded form is

a² + 25 + 10a

Other Algebraic Identity:

• (a - b)² = a² - 2ab + b²
• a² – b²= (a + b)(a – b)
• (x + a)(x + b) = x² + (a + b) x + ab
• (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca
• (a + b)³ = a³ + b³ + 3ab (a + b)
