<h3>What are algebraic expressions?</h3>
Algebraic expressions are seen as expressions that consist of factors, variables, terms, coefficients, and certain constants.
These expressions are also known to be composed of some arithmetic operations, which includes;
- Subtraction
- Addition
- Division
- Multiplication
- Parentheses
- Bracket, etc
Given the expression;
(2x-4)^2=16
√(2x-4)^2 = 16
Find the square root of the expression, we have;
√(2x -4)^2= √16
Find the values
2x - 4 = 4
collect like terms
2x = 4 + 4
Add like terms
2x = 8
Make 'x' the subject of formula
x = 8/2
x = 4
Hence, the value is 4
