1. The problem is to expand the expression or equation given by the user. However, since the user did not provide a specific expression, I will explain the general process of expansion in algebra. 2. Expansion means multiplying out brackets or simplifying expressions by distributing multiplication over addition or subtraction. For example, expanding $(a+b)^2$ means multiplying $(a+b)(a+b)$. 3. The formula for expanding a binomial squared is: $$ (a+b)^2 = a^2 + 2ab + b^2 $$ 4. Important rules: - Use the distributive property: $x(y+z) = xy + xz$ - Multiply each term inside the bracket by the term outside. - Combine like terms after expansion. 5. Example: Expand $(x+3)(x+5)$ $$ (x+3)(x+5) = x(x+5) + 3(x+5) $$ $$ = x^2 + 5x + 3x + 15 $$ $$ = x^2 + 8x + 15 $$ 6. This process applies to any polynomial expansion. Since no specific expression was given, this is a general explanation of expansion.
