The answer is x² + 6x + 9.
Given: (x + 3)²
To find: the solution to the given expression using the algebraic identity
Solution:
The algebraic identity that we need to use in this sum is,
(a + b)² = a² + 2ab + b²
∴ (x + 3)² = x² + 2 × x × 3 + (3)²
= x² + 6x + 9
Answer) x² + 6x + 9
Algebra
- Algebra refers to the mathematical expressions which are created in the form of equations using variables and constants. These expressions are further utilized as formulas, and we can substitute different values in the variables to find out the value of the expression.
- In the given question, we need to use the simple algebraic expression of (a + b)². We need to apply this formula to the given expression to expand the expression.
- Since no number is assigned to x, we cannot find a numerical value of the expression.
- Other algebraic identities include (a - b)², a² - b², and so on.
